all: prepare for release

Use 5-byte entries instead of 4-byte entries to fully preserve "pos".

And add some symbolic constants.

Partially based on a patch by John.

+UPX PULL REQUEST NOTES
+======================
+
+Handling pull requests is actually quite time consuming, so please
+
+- if you want to contribute **a real C++ code bug-fix** then open an issue
+on the main UPX issue tracker first
+
+- if you want to contribute **a new feature** then by all means open an issue
+on the main UPX issue tracker first before starting any coding!
+
+- please refuse the temptation to "improve" the docs, scripts, CI, makefiles,
+cmake build system, spelling errors, etc - we will NOT merge this; only open
+an issue if you're sure there is a **real bug**

+# Security Context
+
+IMPORTANT NOTE: UPX inherits the security context of any files it handles.
+
+This means that packing, unpacking, or even testing or listing a file requires
+the same security considerations as actually executing the file.
+
+Use UPX on trusted files only!

-
-Here are some possible projects from which you can choose if you'd like to
-contribute to UPX. Be sure to get in touch with us first to avoid
-duplicate efforts.
-
-
-User interface:
----------------
-
- - Write a nifty Win32 GUI (in C++), but try to keep the size of the
-   final executable small. Compression should be in a separate
-   thread that calls do_one_file() [see src/work.cpp].
-
- - Draw a nice UPX icon.
-
-
-More formats:
--------------
-
- - Amiga
-
- - BeOS
-
- - C64
-
- - elks/8086 (this is a 16-bit linux-8086 kernel)
-   See http://www.elks.ecs.soton.ac.uk/
-
- - freebsd/386 (generic), freebsd/elf386 (specialized).
-   Probably could share most of the linux code.
-
- - add support for self-extracting HTML pages using a Javascript stub
-   (like the AlgART HTML Packer "AHP")
-
-
-Existing formats:
------------------
-
- - djgpp2/coff: add support for DLX dynamic loading
-     (see SEAL http://www.home.sk/public/seal/ )
-
- - dos/com: add support for very long files - convert to exe if necessary
-
- - dos/exe: implement filter support
-
- - linux/i386:
-     - use the new assembly preprocessor stuff (ie. process the file
-       headers internally)
-     - UPX uncompressor daemon
-     - rewrite the stub in assembly (not sure if this is a good idea...)
-
- - watcom/le: add support for per section compression, LX support, VXD
-
- - win32/pe: display a nice dialog box in the stub in case
-     of problems (like importing a DLL or function fails)
- - win32/pe: per section compression
-
-
-Compression ratio:
-------------------
-
- - invent more effective filters
-
- - I (Markus) will continue to work on better compression algorithms,
-   so be sure to do better than me if you plan working on this ;-)
-

+SECURITY CONTEXT
+================
+
+IMPORTANT NOTE: UPX inherits the security context of any files it handles.
+
+This means that packing, unpacking, or even testing or listing a file requires
+the same security considerations as actually executing the file.
+
+Use UPX on trusted files only!
 
 
 SHORT DOCUMENTATION
 ===================
 
 'upx program.exe' will compress a program or DLL. For best compression
-results try 'upx --brute program.exe'.
+results try 'upx --best program.exe' or 'upx --brute program.exe'.
 
 Please see the file UPX.DOC for the full documentation. The files
 NEWS and BUGS also contain various tidbits of information.
 
 
-DISCLAIMER
-==========
-
-UPX comes with ABSOLUTELY NO WARRANTY; for details see the file LICENSE.
-
-Having said that, we think that UPX is quite stable now. Indeed we
-have compressed lots of files without any problems. Also, the
-current version has undergone several months of beta testing -
-actually it's almost 8 years since our first public beta.
-
-This is the first production quality release, and we plan that future
-releases will be backward compatible with this version.
-
-Please report all problems or suggestions to the authors. Thanks.
-
-
 THE FUTURE
 ==========
 
-  - AArch64 (64-bit ARM) for Linux and iOS.
+  - Stay up-to-date with ongoing OS and executable format changes
 
-  - The Linux approach could probably get ported to a lot of other Unix
-    variants, at least for other i386 architectures it shouldn't be too
-    much work. If someone sends me a fresh hard disk and an official
-    FreeBSD/OpenBSD/NetBSD/Solaris/BeOS... CD I might take a look at it ;-)
+  - RISC-V 64 for Linux
+
+  - ARM64 for Windows (help wanted)
 
   - We will *NOT* add any sort of protection and/or encryption.
     This only gives people a false feeling of security because
-    by definition all protectors/compressors can be broken.
-    And don't trust any advertisement of authors of other executable
-    compressors about this topic - just do a websearch on "unpackers"...
+    all "protectors" can be broken by definition.
 
-  - Fix all remaining bugs - keep your reports coming ;-)

-Introduction
-------------
-
-  Welcome to the UPX source code release!
-
-  UPX is not a toy for kids. Apart from basic knowledge about executables
-  and data compression you will need to be firm in C++, assembler,
-  Perl and Makefiles. Probably some other things as well.
-
-  If you can't manage to compile it then the sources are
-  probably not for you. Don't email us for help.
-
-  The authors use Linux for development. You might want to as well.

 --------------
 
@@ -56,53 +41,68 @@ Short overview
      are #included by the individual executable format handlers.
 
 
-Prerequisites
--------------
-
-  - first of all you need to build the UCL compression library
-    http://www.oberhumer.com/opensource/ucl/
-    Use "CC=gcc -std=gnu89" especially with gcc-6.3 and gcc-7.1.
-    To build for native aarch64 (64-bit ARM) the files config.guess
-    and config.sub must be updated according to the recipe at
-    https://www.gnu.org/software/gettext/manual/html_node/config_002eguess.html
-
-
 Tools needed to build/modify the UPX sources
 --------------------------------------------
 
-  - A C++ compiler: gcc >= 3.3 or clang.
+  - A C++ compiler that fully implements C++17: clang-5, gcc-8 or msvc-2019-16.11
+    (older or other compilers may work but are unsupported, use at your own risk)
 
-  - GNU make 3.81 or better
+  - GNU make
 
-  - zlib and zlib-devel [or zlib-dev] software packages for your
-    host environment
-
-  - LZMA SDK from https://github.com/upx/upx-lzma-sdk
-    When using git run 'git submodule update --init --recursive'.
+  - CMake 3.13 or better; see https://cmake.org/
 
 
 To compile the packer sources
 -----------------------------
 
-  Set the environment variable UPX_UCLDIR to point to your
-  UCL build directory, e.g.
-
-     set UPX_UCLDIR=c:\src\ucl-1.03                   (DOS / Windows)
-     export UPX_UCLDIR=$HOME/local/src/ucl-1.03       (Unix)
-
-  Finally type
-
-     make
+  - just run "make" in the top-level source directory
 
 
 If you want to modify the stub sources you'll also need
 -------------------------------------------------------
 
-  - Perl & Python
+  - Podman/Docker: see misc/podman/rebuild-stubs - this
+    is the preferred way of rebuilding the stubs
+
+  - otherwise you will need:
+    - a Linux host system with Perl, Python2 and some older compat-libs
+    - upx-stubtools - a number of cross-assemblers and cross-compilers.
+      Precompiled binaries for amd64-linux hosts are available from
+      https://github.com/upx/upx-stubtools/releases
+
+
+Developer quick start
+---------------------
+ 1)  $ mkdir my-upx; cd my-upx  # new directory for safety and convenience
+ 2)  $ git clone https://github.com/upx/upx.git
+ 3)  $ git clone https://github.com/upx/upx-testsuite.git
+ 4)  # Optional for re-building stubs:
+ 4a)    $ pushd upx/src/stub  # my-upx/upx/src/stub
+ 4b)    $ wget https://github.com/upx/upx-stubtools/releases/download/v20221212/bin-upx-20221212.tar.xz
+          # Extract to $HOME/bin/bin-upx or $HOME/local/bin/bin-upx.
+          # See directions in: https://github.com/upx/upx-stubtools
+ 4c)    $ make clean; make  # verify that you can re-build stubs
+ 4d)    $ popd  # my-upx
+ 5)  $ cd upx  # my-upx/upx
+ 6)  $ git submodule update --init  # compression algorithms, etc.
+        # DO NOT TOUCH vendor/...
+        # After a git merge/pull/etc, then use "git status"
+        # to check whether the vendor directory is clean;
+        # if not, then update via "git submodule update".
+        # If stuck, then reset via "rm -rf vendor; git submodule update --init".
+ 7)  $ mkdir -p build/debug build/release
+ 8)  $ pushd build/debug  # my-upx/upx/build/debug
+ 9)  $ cmake ../..  # configure cmake
+10)  $ cmake --build . --verbose  # optional "--verbose"
+        # This relies on stub/*.h, which YOU must re-build if necessary.
+        # When in doubt, then use "cd src/stub; make clean; make".
+11)  $ popd  # my-upx/upx
+12)  $ cd src  # my-upx/upx/src
+12a)    On MacOS: install homebrew (https:://brew.sh), then "brew install coreutils"
+        and put <some_prefix>/opt/coreutils/libexec/gnubin into PATH so that
+        "readlink -en" and "sha256sum -b" work.

+
+<p><b>UPX</b> is a portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers <i>*very*</i> fast decompression. Your executables suffer no memory overhead or other drawbacks for most of the formats supported, because of in-place decompression.</p>
+
+<h1 id="DISCLAIMER">DISCLAIMER</h1>
+
+<p><b>UPX</b> comes with ABSOLUTELY NO WARRANTY; for details see the file COPYING.</p>
+
+<p>Please report all problems or suggestions to the authors. Thanks.</p>
+
+<h1 id="SECURITY-CONTEXT">SECURITY CONTEXT</h1>
+
+<p>IMPORTANT NOTE: <b>UPX</b> inherits the security context of any files it handles.</p>
+
+<p>This means that packing, unpacking, or even testing or listing a file requires the same security considerations as actually executing the file.</p>
+
+<p>Use <b>UPX</b> on trusted files only!</p>
+
+<h1 id="DESCRIPTION">DESCRIPTION</h1>
+
+<p><b>UPX</b> is a versatile executable packer with the following features:</p>
+
+<pre><code>- secure: as UPX is documented Open Source since many years any relevant
+    Security/Antivirus software is able to peek inside UPX compressed
+    apps to verify them
+
+- excellent compression ratio: typically compresses better than Zip,
+    use UPX to decrease the size of your distribution !
+
+- very fast decompression: more than 500 MB/sec on any reasonably modern
+    machine
+
+- no memory overhead for your compressed executables for most of the
+    supported formats because of in-place decompression
+
+- safe: you can list, test and unpack your executables.
+    Also, a checksum of both the compressed and uncompressed file is
+    maintained internally.
+
+- universal: UPX can pack a number of executable formats, including
+    Windows programs and DLLs, macOS apps and Linux executables
+
+- portable: UPX is written in portable endian-neutral C++
+
+- extendable: because of the class layout it&#39;s very easy to support
+    new executable formats or add new compression algorithms
+
+- free: UPX is distributed with full source code under the GNU General
+    Public License v2+, with special exceptions granting the free usage
+    for commercial programs</code></pre>

+<h2 id="Decompress">Decompress</h2>
+
+<p>All <b>UPX</b> supported file formats can be unpacked using the <b>-d</b> switch, eg. <b>upx -d yourfile.exe</b> will uncompress the file you&#39;ve just compressed.</p>
+
+<h2 id="Test">Test</h2>
+
+<p>The <b>-t</b> command tests the integrity of the compressed and uncompressed data, eg. <b>upx -t yourfile.exe</b> check whether your file can be safely decompressed. Note, that this command doesn&#39;t check the whole file, only the part that will be uncompressed during program execution. This means that you should not use this command instead of a virus checker.</p>
+
+<h2 id="List">List</h2>
+
+<p>The <b>-l</b> command prints out some information about the compressed files specified on the command line as parameters, eg <b>upx -l yourfile.exe</b> shows the compressed / uncompressed size and the compression ratio of <i>yourfile.exe</i>.</p>

+
+<h1 id="COMPRESSION-LEVELS-TUNING">COMPRESSION LEVELS &amp; TUNING</h1>
+
+<p><b>UPX</b> offers ten different compression levels from <b>-1</b> to <b>-9</b>, and <b>--best</b>. The default compression level is <b>-8</b> for files smaller than 512 KiB, and <b>-7</b> otherwise.</p>
+
+<ul>
+
+<li><p>Compression levels 1, 2 and 3 are pretty fast.</p>
+
+</li>
+<li><p>Compression levels 4, 5 and 6 achieve a good time/ratio performance.</p>
+
+</li>
+<li><p>Compression levels 7, 8 and 9 favor compression ratio over speed.</p>
+
+</li>
+<li><p>Compression level <b>--best</b> may take a long time.</p>
+
+</li>
+</ul>
+
+<p>Note that compression level <b>--best</b> can be somewhat slow for large files, but you definitely should use it when releasing a final version of your program.</p>
+
+<p>Quick info for achieving the best compression ratio:</p>
+
+<ul>
+
+<li><p>Try <b>upx --brute --no-lzma myfile.exe</b> or even <b>upx --ultra-brute --no-lzma myfile.exe</b>.</p>
+
+</li>
+<li><p>The option <b>--lzma</b> enables LZMA compression, which compresses better but is *significantly slower* at decompression. You probably do not want to use it for large files.</p>
+
+<p>(Note that <b>--lzma</b> is automatically enabled by <b>--all-methods</b> and <b>--brute</b>, use <b>--no-lzma</b> to override.)</p>
+
+</li>
+<li><p>Try if <b>--overlay=strip</b> works.</p>
+
+</li>
+<li><p>For win32/pe programs there&#39;s <b>--strip-relocs=0</b>. See notes below.</p>
+
+</li>
+</ul>
+
+<h1 id="OVERLAY-HANDLING-OPTIONS">OVERLAY HANDLING OPTIONS</h1>
+
+<p>Info: An &quot;overlay&quot; means auxiliary data attached after the logical end of an executable, and it often contains application specific data (this is a common practice to avoid an extra data file, though it would be better to use resource sections).</p>
+
+<p><b>UPX</b> handles overlays like many other executable packers do: it simply copies the overlay after the compressed image. This works with some files, but doesn&#39;t work with others, depending on how an application actually accesses this overlaid data.</p>
+
+<pre><code>--overlay=copy    Copy any extra data attached to the file. [DEFAULT]
+
+--overlay=strip   Strip any overlay from the program instead of
+                  copying it. Be warned, this may make the compressed
+                  program crash or otherwise unusable.
+
+--overlay=skip    Refuse to compress any program which has an overlay.</code></pre>
+
+<h1 id="ENVIRONMENT-VARIABLE">ENVIRONMENT VARIABLE</h1>
+
+<p>The environment variable <b>UPX</b> can hold a set of default options for <b>UPX</b>. These options are interpreted first and can be overwritten by explicit command line parameters. For example:</p>
+
+<pre><code>for DOS/Windows:   set UPX=-9 --compress-icons#0
+for sh/ksh/zsh:    UPX=&quot;-9 --compress-icons=0&quot;; export UPX
+for csh/tcsh:      setenv UPX &quot;-9 --compress-icons=0&quot;</code></pre>
+
+<p>Under DOS/Windows you must use &#39;#&#39; instead of &#39;=&#39; when setting the environment variable because of a COMMAND.COM limitation.</p>
+
+<p>Not all of the options are valid in the environment variable - <b>UPX</b> will tell you.</p>
+
+<p>You can explicitly use the <b>--no-env</b> option to ignore the environment variable.</p>

+<p>Introduction</p>
+
+<pre><code>Linux/386 support in UPX consists of 3 different executable formats,
+one optimized for ELF executables (&quot;linux/elf386&quot;), one optimized
+for shell scripts (&quot;linux/sh386&quot;), and one generic format
+(&quot;linux/386&quot;).
+
+We will start with a general discussion first, but please
+also read the relevant docs for each of the individual formats.
+
+Also, there is special support for bootable kernels - see the
+description of the vmlinuz/386 format.</code></pre>
+
+<p>General user&#39;s overview</p>
+
+<pre><code>Running a compressed executable program trades less space on a
+``permanent&#39;&#39; storage medium (such as a hard disk, floppy disk,
+CD-ROM, flash memory, EPROM, etc.) for more space in one or more
+``temporary&#39;&#39; storage media (such as RAM, swap space, /tmp, etc.).
+Running a compressed executable also requires some additional CPU
+cycles to generate the compressed executable in the first place,
+and to decompress it at each invocation.
+
+How much space is traded?  It depends on the executable, but many
+programs save 30% to 50% of permanent disk space.  How much CPU
+overhead is there?  Again, it depends on the executable, but
+decompression speed generally is at least many megabytes per second,
+and frequently is limited by the speed of the underlying disk
+or network I/O.
+
+Depending on the statistics of usage and access, and the relative
+speeds of CPU, RAM, swap space, /tmp, and file system storage, then
+invoking and running a compressed executable can be faster than
+directly running the corresponding uncompressed program.
+The operating system might perform fewer expensive I/O operations
+to invoke the compressed program.  Paging to or from swap space
+or /tmp might be faster than paging from the general file system.
+``Medium-sized&#39;&#39; programs which access about 1/3 to 1/2 of their
+stored program bytes can do particularly well with compression.
+Small programs tend not to benefit as much because the absolute
+savings is less.  Big programs tend not to benefit proportionally
+because each invocation may use only a small fraction of the program,
+yet UPX decompresses the entire program before invoking it.
+But in environments where disk or flash memory storage is limited,
+then compression may win anyway.
+
+Currently, executables compressed by UPX do not share RAM at runtime
+in the way that executables mapped from a file system do.  As a
+result, if the same program is run simultaneously by more than one
+process, then using the compressed version will require more RAM and/or
+swap space.  So, shell programs (bash, csh, etc.)  and ``make&#39;&#39;
+might not be good candidates for compression.
+
+UPX recognizes three executable formats for Linux: Linux/elf386,
+Linux/sh386, and Linux/386.  Linux/386 is the most generic format;
+it accommodates any file that can be executed.  At runtime, the UPX
+decompression stub re-creates in /tmp a copy of the original file,
+and then the copy is (re-)executed with the same arguments.
+ELF binary executables prefer the Linux/elf386 format by default,
+because UPX decompresses them directly into RAM, uses only one
+exec, does not use space in /tmp, and does not use /proc.
+Shell scripts where the underlying shell accepts a ``-c&#39;&#39; argument
+can use the Linux/sh386 format.  UPX decompresses the shell script
+into low memory, then maps the shell and passes the entire text of the
+script as an argument with a leading ``-c&#39;&#39;.</code></pre>
+
+<p>General benefits:</p>
+
+<pre><code>- UPX can compress all executables, be it AOUT, ELF, libc4, libc5,
+  libc6, Shell/Perl/Python/... scripts, standalone Java .class
+  binaries, or whatever...
+  All scripts and programs will work just as before.
+
+- Compressed programs are completely self-contained. No need for
+  any external program.
+
+- UPX keeps your original program untouched. This means that
+  after decompression you will have a byte-identical version,
+  and you can use UPX as a file compressor just like gzip.
+  [ Note that UPX maintains a checksum of the file internally,
+    so it is indeed a reliable alternative. ]
+
+- As the stub only uses syscalls and isn&#39;t linked against libc it
+  should run under any Linux configuration that can run ELF
+  binaries.
+
+- For the same reason compressed executables should run under
+  FreeBSD and other systems which can run Linux binaries.
+  [ Please send feedback on this topic ]</code></pre>
+
+<p>General drawbacks:</p>
+
+<pre><code>- It is not advisable to compress programs which usually have many
+  instances running (like `sh&#39; or `make&#39;) because the common segments of
+  compressed programs won&#39;t be shared any longer between different
+  processes.
+
+- `ldd&#39; and `size&#39; won&#39;t show anything useful because all they
+  see is the statically linked stub.  Since version 0.82 the section
+  headers are stripped from the UPX stub and `size&#39; doesn&#39;t even
+  recognize the file format.  The file patches/patch-elfcode.h has a
+  patch to fix this bug in `size&#39; and other programs which use GNU BFD.</code></pre>
+
+<p>General notes:</p>
+
+<pre><code>- As UPX leaves your original program untouched it is advantageous
+  to strip it before compression.
+
+- If you compress a script you will lose platform independence -
+  this could be a problem if you are using NFS mounted disks.
+
+- Compression of suid, guid and sticky-bit programs is rejected
+  because of possible security implications.
+
+- For the same reason there is no sense in making any compressed
+  program suid.
+
+- Obviously UPX won&#39;t work with executables that want to read data
+  from themselves. E.g., this might be a problem for Perl scripts
+  which access their __DATA__ lines.
+
+- In case of internal errors the stub will abort with exitcode 127.
+  Typical reasons for this to happen are that the program has somehow
+  been modified after compression.
+  Running `strace -o strace.log compressed_file&#39; will tell you more.</code></pre>

+
+<p>The generic linux/386 format decompresses to /tmp and needs /proc file system support. It starts the decompressed program via the execve() syscall.</p>
+
+<p>Linux/386 is only selected if the specialized linux/elf386 and linux/sh386 won&#39;t recognize a file.</p>
+
+<p>Packed programs will be byte-identical to the original after uncompression.</p>
+
+<p>How it works:</p>
+
+<pre><code>For files which are not ELF and not a script for a known &quot;-c&quot; shell,
+UPX uses kernel execve(), which first requires decompressing to a
+temporary file in the file system.  Interestingly -
+because of the good memory management of the Linux kernel - this
+often does not introduce a noticeable delay, and in fact there
+will be no disk access at all if you have enough free memory as
+the entire process takes places within the file system buffers.
+
+A compressed executable consists of the UPX stub and an overlay
+which contains the original program in a compressed form.
+
+The UPX stub is a statically linked ELF executable and does
+the following at program startup:
+
+  1) decompress the overlay to a temporary location in /tmp
+  2) open the temporary file for reading
+  3) try to delete the temporary file and start (execve)
+     the uncompressed program in /tmp using /proc/&lt;pid&gt;/fd/X as
+     attained by step 2)
+  4) if that fails, fork off a subprocess to clean up and
+     start the program in /tmp in the meantime
+
+The UPX stub is about 1700 bytes long, partly written in assembler
+and only uses kernel syscalls. It is not linked against any libc.</code></pre>
+
+<p>Specific drawbacks:</p>
+
+<pre><code>- You need additional free disk space for the uncompressed program
+  in your /tmp directory. This program is deleted immediately after
+  decompression, but you still need it for the full execution time
+  of the program.
+
+- You must have /proc file system support as the stub wants to open
+  /proc/&lt;pid&gt;/exe and needs /proc/&lt;pid&gt;/fd/X. This also means that you
+  cannot compress programs that are used during the boot sequence
+  before /proc is mounted.
+
+- Utilities like `top&#39; will display numerical values in the process
+  name field. This is because Linux computes the process name from
+  the first argument of the last execve syscall (which is typically
+  something like /proc/&lt;pid&gt;/fd/3).
+
+- Because of temporary decompression to disk the decompression speed
+  is not as fast as with the other executable formats. Still, I can see
+  no noticeable delay when starting programs like my ~3 MiB emacs (which
+  is less than 1 MiB when compressed :-).</code></pre>
+
+<p>Extra options available for this executable format:</p>
+
+<pre><code>--force-execve      Force the use of the generic linux/386 &quot;execve&quot;

+

+
+<pre><code>- UPX creates as default a suitable executable for CD-Mastering

+  the special option &quot;--boot-only&quot; as described below.
+  It has been reported that upx packed executables are fully compatible with
+  the Sony PlayStation 2 (PS2, PStwo) and Sony PlayStation Portable (PSP) in
+  Sony PlayStation (PSone) emulation mode.
+
+- Normally the packed files use the same memory areas like the uncompressed
+  versions, so they will not override other memory areas while unpacking.
+  If this isn&#39;t possible UPX will abort showing a &#39;packed data overlap&#39;

+
+<p>The PE support in <b>UPX</b> is quite stable now, but probably there are still some incompatibilities with some files.</p>
+
+<p>Because of the way <b>UPX</b> (and other packers for this format) works, you can see increased memory usage of your compressed files because the whole program is loaded into memory at startup. If you start several instances of huge compressed programs you&#39;re wasting memory because the common segments of the program won&#39;t get shared across the instances. On the other hand if you&#39;re compressing only smaller programs, or running only one instance of larger programs, then this penalty is smaller, but it&#39;s still there.</p>
+
+<p>If you&#39;re running executables from network, then compressed programs will load faster, and require less bandwidth during execution.</p>
+
+<p>DLLs are supported. But UPX compressed DLLs can not share common data and code when they got used by multiple applications. So compressing msvcrt.dll is a waste of memory, but compressing the dll plugins of a particular application may be a better idea.</p>
+
+<p>Screensavers are supported, with the restriction that the filename must end with &quot;.scr&quot; (as screensavers are handled slightly different than normal exe files).</p>

+                     identifier of the resource. It can be a decimal number
+                     or a string. For example:
+
+                     --keep-resource=2/MYBITMAP,5,6/12345
+
+                     UPX won&#39;t compress the named bitmap resource &quot;MYBITMAP&quot;,
+                     it leaves every dialog (5) resource uncompressed, and
+                     it won&#39;t touch the string table resource with identifier
+                     12345.
+
+ --force             Force compression even when there is an
+                     unexpected value in a header field.
+                     Use with care.
+
+ --strip-relocs=0    Don&#39;t strip relocation records.
+ --strip-relocs=1    Strip relocation records. [DEFAULT]
+                     This option only works on executables with base
+                     address greater or equal to 0x400000. Usually the
+                     compressed files becomes smaller, but some files
+                     may become larger. Note that the resulting file will
+                     not work under Windows 3.x (Win32s).
+                     UPX never strips relocations from a DLL
+                     regardless of this option.
+
+ --all-methods       Compress the program several times, using all
+                     available compression methods. This may improve
+                     the compression ratio in some cases, but usually
+                     the default method gives the best results anyway.
+
+ --all-filters       Compress the program several times, using all
+                     available preprocessing filters. This may improve
+                     the compression ratio in some cases, but usually
+                     the default filter gives the best results anyway.</code></pre>

+ABSTRACT
+                        The Ultimate Packer for eXecutables
+       Copyright (c) 1996-2024 Markus Oberhumer, Laszlo Molnar & John Reiser
+                               https://upx.github.io
+
+    UPX is a portable, extendable, high-performance executable packer for
+    several different executable formats. It achieves an excellent
+    compression ratio and offers **very** fast decompression. Your
+    executables suffer no memory overhead or other drawbacks for most of the
+    formats supported, because of in-place decompression.
+
+DISCLAIMER
+    UPX comes with ABSOLUTELY NO WARRANTY; for details see the file COPYING.
+
+    Please report all problems or suggestions to the authors. Thanks.
+
+SECURITY CONTEXT
+    IMPORTANT NOTE: UPX inherits the security context of any files it
+    handles.
+
+    This means that packing, unpacking, or even testing or listing a file
+    requires the same security considerations as actually executing the
+    file.
+
+    Use UPX on trusted files only!
+
+DESCRIPTION
+    UPX is a versatile executable packer with the following features:
+
+      - secure: as UPX is documented Open Source since many years any relevant
+          Security/Antivirus software is able to peek inside UPX compressed
+          apps to verify them
+
+      - excellent compression ratio: typically compresses better than Zip,
+          use UPX to decrease the size of your distribution !
+
+      - very fast decompression: more than 500 MB/sec on any reasonably modern
+          machine
+
+      - no memory overhead for your compressed executables for most of the
+          supported formats because of in-place decompression
+
+      - safe: you can list, test and unpack your executables.
+          Also, a checksum of both the compressed and uncompressed file is
+          maintained internally.
+
+      - universal: UPX can pack a number of executable formats, including
+          Windows programs and DLLs, macOS apps and Linux executables
+
+      - portable: UPX is written in portable endian-neutral C++
+
+      - extendable: because of the class layout it's very easy to support
+          new executable formats or add new compression algorithms
+
+      - free: UPX is distributed with full source code under the GNU General
+          Public License v2+, with special exceptions granting the free usage
+          for commercial programs
+
+    You probably understand now why we call UPX the "*ultimate*" executable
+    packer.
+
+COMMANDS
+  Compress
+    This is the default operation, eg. upx yourfile.exe will compress the
+    file specified on the command line.
+
+  Decompress
+    All UPX supported file formats can be unpacked using the -d switch, eg.
+    upx -d yourfile.exe will uncompress the file you've just compressed.
+
+  Test
+    The -t command tests the integrity of the compressed and uncompressed
+    data, eg. upx -t yourfile.exe check whether your file can be safely
+    decompressed. Note, that this command doesn't check the whole file, only
+    the part that will be uncompressed during program execution. This means
+    that you should not use this command instead of a virus checker.
+
+  List
+    The -l command prints out some information about the compressed files
+    specified on the command line as parameters, eg upx -l yourfile.exe
+    shows the compressed / uncompressed size and the compression ratio of
+    *yourfile.exe*.
+
+OPTIONS
+    -q: be quiet, suppress warnings
+
+    -q -q (or -qq): be very quiet, suppress errors
+
+    -q -q -q (or -qqq): produce no output at all
+
+    --help: prints the help
+
+    --version: print the version of UPX
+
+    --exact: when compressing, require to be able to get a byte-identical
+    file after decompression with option -d. [NOTE: this is work in progress
+    and is not supported for all formats yet. If you do care, as a
+    workaround you can compress and then decompress your program a first
+    time - any further compress-decompress steps should then yield
+    byte-identical results as compared to the first decompressed version.]
+
+    -k: keep backup files
+
+    -o file: write output to file
+
+    [ ...more docs need to be written... - type `upx --help' for now ]
+
+COMPRESSION LEVELS & TUNING
+    UPX offers ten different compression levels from -1 to -9, and --best.
+    The default compression level is -8 for files smaller than 512 KiB, and
+    -7 otherwise.
+
+    *   Compression levels 1, 2 and 3 are pretty fast.
+
+    *   Compression levels 4, 5 and 6 achieve a good time/ratio performance.
+
+    *   Compression levels 7, 8 and 9 favor compression ratio over speed.
+
+    *   Compression level --best may take a long time.
+
+    Note that compression level --best can be somewhat slow for large files,
+    but you definitely should use it when releasing a final version of your
+    program.
+
+    Quick info for achieving the best compression ratio:
+
+    *   Try upx --brute --no-lzma myfile.exe or even upx --ultra-brute
+        --no-lzma myfile.exe.
+
+    *   The option --lzma enables LZMA compression, which compresses better
+        but is *significantly slower* at decompression. You probably do not
+        want to use it for large files.
+
+        (Note that --lzma is automatically enabled by --all-methods and
+        --brute, use --no-lzma to override.)
+
+    *   Try if --overlay=strip works.
+
+    *   For win32/pe programs there's --strip-relocs=0. See notes below.
+
+OVERLAY HANDLING OPTIONS
+    Info: An "overlay" means auxiliary data attached after the logical end
+    of an executable, and it often contains application specific data (this
+    is a common practice to avoid an extra data file, though it would be
+    better to use resource sections).
+
+    UPX handles overlays like many other executable packers do: it simply
+    copies the overlay after the compressed image. This works with some
+    files, but doesn't work with others, depending on how an application
+    actually accesses this overlaid data.
+
+      --overlay=copy    Copy any extra data attached to the file. [DEFAULT]
+
+      --overlay=strip   Strip any overlay from the program instead of
+                        copying it. Be warned, this may make the compressed
+                        program crash or otherwise unusable.
+
+      --overlay=skip    Refuse to compress any program which has an overlay.
+
+ENVIRONMENT VARIABLE
+    The environment variable UPX can hold a set of default options for UPX.
+    These options are interpreted first and can be overwritten by explicit
+    command line parameters. For example:
+
+        for DOS/Windows:   set UPX=-9 --compress-icons#0
+        for sh/ksh/zsh:    UPX="-9 --compress-icons=0"; export UPX
+        for csh/tcsh:      setenv UPX "-9 --compress-icons=0"
+
+    Under DOS/Windows you must use '#' instead of '=' when setting the
+    environment variable because of a COMMAND.COM limitation.
+
+    Not all of the options are valid in the environment variable - UPX will
+    tell you.
+
+    You can explicitly use the --no-env option to ignore the environment
+    variable.
+
+NOTES FOR THE SUPPORTED EXECUTABLE FORMATS
+  NOTES FOR ATARI/TOS
+    This is the executable format used by the Atari ST/TT, a Motorola 68000
+    based personal computer which was popular in the late '80s. Support of
+    this format is only because of nostalgic feelings of one of the authors
+    and serves no practical purpose :-). See https://freemint.github.io for
+    more info.
+
+    Packed programs will be byte-identical to the original after
+    uncompression. All debug information will be stripped, though.
+
+    Extra options available for this executable format:
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+  NOTES FOR BVMLINUZ/I386
+    Same as vmlinuz/i386.
+
+  NOTES FOR DOS/COM
+    Obviously UPX won't work with executables that want to read data from
+    themselves (like some commandline utilities that ship with Win95/98/ME).
+
+    Compressed programs only work on a 286+.
+
+    Packed programs will be byte-identical to the original after
+    uncompression.
+
+    Maximum uncompressed size: ~65100 bytes.
+
+    Extra options available for this executable format:
+
+      --8086              Create an executable that works on any 8086 CPU.
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+      --all-filters       Compress the program several times, using all
+                          available preprocessing filters. This may improve
+                          the compression ratio in some cases, but usually
+                          the default filter gives the best results anyway.
+
+  NOTES FOR DOS/EXE
+    dos/exe stands for all "normal" 16-bit DOS executables.
+
+    Obviously UPX won't work with executables that want to read data from
+    themselves (like some command line utilities that ship with
+    Win95/98/ME).
+
+    Compressed programs only work on a 286+.
+
+    Extra options available for this executable format:
+
+      --8086              Create an executable that works on any 8086 CPU.
+
+      --no-reloc          Use no relocation records in the exe header.
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+  NOTES FOR DOS/SYS
+    Compressed programs only work on a 286+.
+
+    Packed programs will be byte-identical to the original after
+    uncompression.
+
+    Maximum uncompressed size: ~65350 bytes.
+
+    Extra options available for this executable format:
+
+      --8086              Create an executable that works on any 8086 CPU.
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+      --all-filters       Compress the program several times, using all
+                          available preprocessing filters. This may improve
+                          the compression ratio in some cases, but usually
+                          the default filter gives the best results anyway.
+
+  NOTES FOR DJGPP2/COFF
+    First of all, it is recommended to use UPX *instead* of strip. strip has
+    the very bad habit of replacing your stub with its own (outdated)
+    version. Additionally UPX corrects a bug/feature in strip v2.8.x: it
+    will fix the 4 KiB alignment of the stub.
+
+    UPX includes the full functionality of stubify. This means it will
+    automatically stubify your COFF files. Use the option --coff to disable
+    this functionality (see below).
+
+    UPX automatically handles Allegro packfiles.
+
+    The DLM format (a rather exotic shared library extension) is not
+    supported.
+
+    Packed programs will be byte-identical to the original after
+    uncompression. All debug information and trailing garbage will be
+    stripped, though.
+
+    Extra options available for this executable format:
+
+      --coff              Produce COFF output instead of EXE. By default
+                          UPX keeps your current stub.
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+      --all-filters       Compress the program several times, using all
+                          available preprocessing filters. This may improve
+                          the compression ratio in some cases, but usually
+                          the default filter gives the best results anyway.
+
+  NOTES FOR LINUX [general]
+    Introduction
+
+      Linux/386 support in UPX consists of 3 different executable formats,
+      one optimized for ELF executables ("linux/elf386"), one optimized
+      for shell scripts ("linux/sh386"), and one generic format
+      ("linux/386").
+
+      We will start with a general discussion first, but please
+      also read the relevant docs for each of the individual formats.
+
+      Also, there is special support for bootable kernels - see the
+      description of the vmlinuz/386 format.
+
+    General user's overview
+
+      Running a compressed executable program trades less space on a
+      ``permanent'' storage medium (such as a hard disk, floppy disk,
+      CD-ROM, flash memory, EPROM, etc.) for more space in one or more
+      ``temporary'' storage media (such as RAM, swap space, /tmp, etc.).
+      Running a compressed executable also requires some additional CPU
+      cycles to generate the compressed executable in the first place,
+      and to decompress it at each invocation.
+
+      How much space is traded?  It depends on the executable, but many
+      programs save 30% to 50% of permanent disk space.  How much CPU
+      overhead is there?  Again, it depends on the executable, but
+      decompression speed generally is at least many megabytes per second,
+      and frequently is limited by the speed of the underlying disk
+      or network I/O.
+
+      Depending on the statistics of usage and access, and the relative
+      speeds of CPU, RAM, swap space, /tmp, and file system storage, then
+      invoking and running a compressed executable can be faster than
+      directly running the corresponding uncompressed program.
+      The operating system might perform fewer expensive I/O operations
+      to invoke the compressed program.  Paging to or from swap space
+      or /tmp might be faster than paging from the general file system.
+      ``Medium-sized'' programs which access about 1/3 to 1/2 of their
+      stored program bytes can do particularly well with compression.
+      Small programs tend not to benefit as much because the absolute
+      savings is less.  Big programs tend not to benefit proportionally
+      because each invocation may use only a small fraction of the program,
+      yet UPX decompresses the entire program before invoking it.
+      But in environments where disk or flash memory storage is limited,
+      then compression may win anyway.
+
+      Currently, executables compressed by UPX do not share RAM at runtime
+      in the way that executables mapped from a file system do.  As a
+      result, if the same program is run simultaneously by more than one
+      process, then using the compressed version will require more RAM and/or
+      swap space.  So, shell programs (bash, csh, etc.)  and ``make''
+      might not be good candidates for compression.
+
+      UPX recognizes three executable formats for Linux: Linux/elf386,
+      Linux/sh386, and Linux/386.  Linux/386 is the most generic format;
+      it accommodates any file that can be executed.  At runtime, the UPX
+      decompression stub re-creates in /tmp a copy of the original file,
+      and then the copy is (re-)executed with the same arguments.
+      ELF binary executables prefer the Linux/elf386 format by default,
+      because UPX decompresses them directly into RAM, uses only one
+      exec, does not use space in /tmp, and does not use /proc.
+      Shell scripts where the underlying shell accepts a ``-c'' argument
+      can use the Linux/sh386 format.  UPX decompresses the shell script
+      into low memory, then maps the shell and passes the entire text of the
+      script as an argument with a leading ``-c''.
+
+    General benefits:
+
+      - UPX can compress all executables, be it AOUT, ELF, libc4, libc5,
+        libc6, Shell/Perl/Python/... scripts, standalone Java .class
+        binaries, or whatever...
+        All scripts and programs will work just as before.
+
+      - Compressed programs are completely self-contained. No need for
+        any external program.
+
+      - UPX keeps your original program untouched. This means that
+        after decompression you will have a byte-identical version,
+        and you can use UPX as a file compressor just like gzip.
+        [ Note that UPX maintains a checksum of the file internally,
+          so it is indeed a reliable alternative. ]
+
+      - As the stub only uses syscalls and isn't linked against libc it
+        should run under any Linux configuration that can run ELF
+        binaries.
+
+      - For the same reason compressed executables should run under
+        FreeBSD and other systems which can run Linux binaries.
+        [ Please send feedback on this topic ]
+
+    General drawbacks:
+
+      - It is not advisable to compress programs which usually have many
+        instances running (like `sh' or `make') because the common segments of
+        compressed programs won't be shared any longer between different
+        processes.
+
+      - `ldd' and `size' won't show anything useful because all they
+        see is the statically linked stub.  Since version 0.82 the section
+        headers are stripped from the UPX stub and `size' doesn't even
+        recognize the file format.  The file patches/patch-elfcode.h has a
+        patch to fix this bug in `size' and other programs which use GNU BFD.
+
+    General notes:
+
+      - As UPX leaves your original program untouched it is advantageous
+        to strip it before compression.
+
+      - If you compress a script you will lose platform independence -
+        this could be a problem if you are using NFS mounted disks.
+
+      - Compression of suid, guid and sticky-bit programs is rejected
+        because of possible security implications.
+
+      - For the same reason there is no sense in making any compressed
+        program suid.
+
+      - Obviously UPX won't work with executables that want to read data
+        from themselves. E.g., this might be a problem for Perl scripts
+        which access their __DATA__ lines.
+
+      - In case of internal errors the stub will abort with exitcode 127.
+        Typical reasons for this to happen are that the program has somehow
+        been modified after compression.
+        Running `strace -o strace.log compressed_file' will tell you more.
+
+  NOTES FOR LINUX/ELF386
+    Please read the general Linux description first.
+
+    The linux/elf386 format decompresses directly into RAM, uses only one
+    exec, does not use space in /tmp, and does not use /proc.
+
+    Linux/elf386 is automatically selected for Linux ELF executables.
+
+    Packed programs will be byte-identical to the original after
+    uncompression.
+
+    How it works:
+
+      For ELF executables, UPX decompresses directly to memory, simulating
+      the mapping that the operating system kernel uses during exec(),
+      including the PT_INTERP program interpreter (if any).
+      The brk() is set by a special PT_LOAD segment in the compressed
+      executable itself.  UPX then wipes the stack clean except for
+      arguments, environment variables, and Elf_auxv entries (this is
+      required by bugs in the startup code of /lib/ld-linux.so as of
+      May 2000), and transfers control to the program interpreter or
+      the e_entry address of the original executable.
+
+      The UPX stub is about 1700 bytes long, partly written in assembler
+      and only uses kernel syscalls. It is not linked against any libc.
+
+    Specific drawbacks:
+
+      - For linux/elf386 and linux/sh386 formats, you will be relying on
+        RAM and swap space to hold all of the decompressed program during
+        the lifetime of the process.  If you already use most of your swap
+        space, then you may run out.  A system that is "out of memory"
+        can become fragile.  Many programs do not react gracefully when
+        malloc() returns 0.  With newer Linux kernels, the kernel
+        may decide to kill some processes to regain memory, and you
+        may not like the kernel's choice of which to kill.  Running
+        /usr/bin/top is one way to check on the usage of swap space.
+
+    Extra options available for this executable format:
+
+      (none)
+
+  NOTES FOR LINUX/SH386
+    Please read the general Linux description first.
+
+    Shell scripts where the underling shell accepts a ``-c'' argument can
+    use the Linux/sh386 format. UPX decompresses the shell script into low
+    memory, then maps the shell and passes the entire text of the script as
+    an argument with a leading ``-c''. It does not use space in /tmp, and
+    does not use /proc.
+
+    Linux/sh386 is automatically selected for shell scripts that use a known
+    shell.
+
+    Packed programs will be byte-identical to the original after
+    uncompression.
+
+    How it works:
+
+      For shell script executables (files beginning with "#!/" or "#! /")
+      where the shell is known to accept "-c <command>", UPX decompresses
+      the file into low memory, then maps the shell (and its PT_INTERP),
+      and passes control to the shell with the entire decompressed file
+      as the argument after "-c".  Known shells are sh, ash, bash, bsh, csh,
+      ksh, tcsh, pdksh.  Restriction: UPX cannot use this method
+      for shell scripts which use the one optional string argument after
+      the shell name in the script (example: "#! /bin/sh option3\n".)
+
+      The UPX stub is about 1700 bytes long, partly written in assembler
+      and only uses kernel syscalls. It is not linked against any libc.
+
+    Specific drawbacks:
+
+      - For linux/elf386 and linux/sh386 formats, you will be relying on
+        RAM and swap space to hold all of the decompressed program during
+        the lifetime of the process.  If you already use most of your swap
+        space, then you may run out.  A system that is "out of memory"

+
+    Extra options available for this executable format:
+
+      (none)
+
+  NOTES FOR LINUX/386
+    Please read the general Linux description first.
+
+    The generic linux/386 format decompresses to /tmp and needs /proc file
+    system support. It starts the decompressed program via the execve()
+    syscall.
+
+    Linux/386 is only selected if the specialized linux/elf386 and
+    linux/sh386 won't recognize a file.
+
+    Packed programs will be byte-identical to the original after
+    uncompression.
+
+    How it works:
+
+      For files which are not ELF and not a script for a known "-c" shell,
+      UPX uses kernel execve(), which first requires decompressing to a
+      temporary file in the file system.  Interestingly -
+      because of the good memory management of the Linux kernel - this
+      often does not introduce a noticeable delay, and in fact there
+      will be no disk access at all if you have enough free memory as
+      the entire process takes places within the file system buffers.
+
+      A compressed executable consists of the UPX stub and an overlay
+      which contains the original program in a compressed form.
+
+      The UPX stub is a statically linked ELF executable and does
+      the following at program startup:
+
+        1) decompress the overlay to a temporary location in /tmp
+        2) open the temporary file for reading
+        3) try to delete the temporary file and start (execve)
+           the uncompressed program in /tmp using /proc/<pid>/fd/X as
+           attained by step 2)
+        4) if that fails, fork off a subprocess to clean up and
+           start the program in /tmp in the meantime
+
+      The UPX stub is about 1700 bytes long, partly written in assembler
+      and only uses kernel syscalls. It is not linked against any libc.
+
+    Specific drawbacks:
+
+      - You need additional free disk space for the uncompressed program
+        in your /tmp directory. This program is deleted immediately after
+        decompression, but you still need it for the full execution time
+        of the program.
+
+      - You must have /proc file system support as the stub wants to open
+        /proc/<pid>/exe and needs /proc/<pid>/fd/X. This also means that you
+        cannot compress programs that are used during the boot sequence
+        before /proc is mounted.
+
+      - Utilities like `top' will display numerical values in the process
+        name field. This is because Linux computes the process name from
+        the first argument of the last execve syscall (which is typically
+        something like /proc/<pid>/fd/3).
+
+      - Because of temporary decompression to disk the decompression speed
+        is not as fast as with the other executable formats. Still, I can see
+        no noticeable delay when starting programs like my ~3 MiB emacs (which
+        is less than 1 MiB when compressed :-).
+
+    Extra options available for this executable format:
+
+      --force-execve      Force the use of the generic linux/386 "execve"
+                          format, i.e. do not try the linux/elf386 and
+                          linux/sh386 formats.
+
+  NOTES FOR PS1/EXE
+    This is the executable format used by the Sony PlayStation (PSone), a
+    MIPS R3000 based gaming console which is popular since the late '90s.
+    Support of this format is very similar to the Atari one, because of
+    nostalgic feelings of one of the authors.
+
+    Packed programs will be byte-identical to the original after
+    uncompression, until further notice.
+
+    Maximum uncompressed size: ~1.89 / ~7.60 MiB.
+
+    Notes:
+
+      - UPX creates as default a suitable executable for CD-Mastering
+        and console transfer. For a CD-Master main executable you could also try
+        the special option "--boot-only" as described below.
+        It has been reported that upx packed executables are fully compatible with
+        the Sony PlayStation 2 (PS2, PStwo) and Sony PlayStation Portable (PSP) in
+        Sony PlayStation (PSone) emulation mode.
+
+      - Normally the packed files use the same memory areas like the uncompressed
+        versions, so they will not override other memory areas while unpacking.
+        If this isn't possible UPX will abort showing a 'packed data overlap'
+        error. With the "--force" option UPX will relocate the loading address
+        for the packed file, but this isn't a real problem if it is a single or
+        the main executable.
+
+    Extra options available for this executable format:
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+      --8-bit             Uses 8 bit size compression [default: 32 bit]
+
+      --8mib-ram          PSone has 8 MiB ram available [default: 2 MiB]
+
+      --boot-only         This format is for main exes and CD-Mastering only !
+                          It may slightly improve the compression ratio,
+                          decompression routines are faster than default ones.
+                          But it cannot be used for console transfer !
+
+      --no-align          This option disables CD mode 2 data sector format
+                          alignment. May slightly improves the compression ratio,
+                          but the compressed executable will not boot from a CD.
+                          Use it for console transfer only !
+
+  NOTES FOR RTM32/PE and ARM/PE
+    Same as win32/pe.
+
+  NOTES FOR TMT/ADAM
+    This format is used by the TMT Pascal compiler - see http://www.tmt.com/
+    .
+
+    Extra options available for this executable format:
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+      --all-filters       Compress the program several times, using all
+                          available preprocessing filters. This may improve
+                          the compression ratio in some cases, but usually
+                          the default filter gives the best results anyway.
+
+  NOTES FOR VMLINUZ/386
+    The vmlinuz/386 and bvmlinuz/386 formats take a gzip-compressed bootable
+    Linux kernel image ("vmlinuz", "zImage", "bzImage"), gzip-decompress it
+    and re-compress it with the UPX compression method.
+
+    vmlinuz/386 is completely unrelated to the other Linux executable
+    formats, and it does not share any of their drawbacks.
+
+    Notes:
+
+      - Be sure that "vmlinuz/386" or "bvmlinuz/386" is displayed
+      during compression - otherwise a wrong executable format
+      may have been used, and the kernel won't boot.
+
+    Benefits:
+
+      - Better compression (but note that the kernel was already compressed,
+      so the improvement is not as large as with other formats).
+      Still, the bytes saved may be essential for special needs like
+      boot disks.
+
+         For example, this is what I get for my 2.2.16 kernel:
+            1589708  vmlinux
+             641073  bzImage        [original]
+             560755  bzImage.upx    [compressed by "upx -9"]
+
+      - Much faster decompression at kernel boot time (but kernel
+        decompression speed is not really an issue these days).
+
+    Drawbacks:
+
+      (none)
+
+    Extra options available for this executable format:

+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+      --all-filters       Compress the program several times, using all
+                          available preprocessing filters. This may improve
+                          the compression ratio in some cases, but usually
+                          the default filter gives the best results anyway.
+
+  NOTES FOR WATCOM/LE
+    UPX has been successfully tested with the following extenders: DOS4G,
+    DOS4GW, PMODE/W, DOS32a, CauseWay. The WDOS/X extender is partly
+    supported (for details see the file bugs BUGS).
+
+    DLLs and the LX format are not supported.
+
+    Extra options available for this executable format:
+
+      --le                Produce an unbound LE output instead of
+                          keeping the current stub.
+
+  NOTES FOR WIN32/PE
+    The PE support in UPX is quite stable now, but probably there are still
+    some incompatibilities with some files.
+
+    Because of the way UPX (and other packers for this format) works, you
+    can see increased memory usage of your compressed files because the
+    whole program is loaded into memory at startup. If you start several
+    instances of huge compressed programs you're wasting memory because the
+    common segments of the program won't get shared across the instances. On
+    the other hand if you're compressing only smaller programs, or running
+    only one instance of larger programs, then this penalty is smaller, but
+    it's still there.
+
+    If you're running executables from network, then compressed programs
+    will load faster, and require less bandwidth during execution.
+
+    DLLs are supported. But UPX compressed DLLs can not share common data
+    and code when they got used by multiple applications. So compressing
+    msvcrt.dll is a waste of memory, but compressing the dll plugins of a
+    particular application may be a better idea.
+
+    Screensavers are supported, with the restriction that the filename must
+    end with ".scr" (as screensavers are handled slightly different than
+    normal exe files).
+
+    UPX compressed PE files have some minor memory overhead (usually in the
+    10 - 30 KiB range) which can be seen by specifying the "-i" command line
+    switch during compression.
+
+    Extra options available for this executable format:
+
+     --compress-exports=0 Don't compress the export section.
+                          Use this if you plan to run the compressed
+                          program under Wine.
+     --compress-exports=1 Compress the export section. [DEFAULT]
+                          Compression of the export section can improve the
+                          compression ratio quite a bit but may not work
+                          with all programs (like winword.exe).
+                          UPX never compresses the export section of a DLL
+                          regardless of this option.
+
+      --compress-icons=0  Don't compress any icons.
+      --compress-icons=1  Compress all but the first icon.
+      --compress-icons=2  Compress all icons which are not in the
+                          first icon directory. [DEFAULT]
+      --compress-icons=3  Compress all icons.
+
+      --compress-resources=0  Don't compress any resources at all.
+
+      --keep-resource=list Don't compress resources specified by the list.
+                          The members of the list are separated by commas.
+                          A list member has the following format: I<type[/name]>.
+                          I<Type> is the type of the resource. Standard types
+                          must be specified as decimal numbers, user types can be
+                          specified by decimal IDs or strings. I<Name> is the
+                          identifier of the resource. It can be a decimal number
+                          or a string. For example:
+
+                          --keep-resource=2/MYBITMAP,5,6/12345
+
+                          UPX won't compress the named bitmap resource "MYBITMAP",
+                          it leaves every dialog (5) resource uncompressed, and
+                          it won't touch the string table resource with identifier
+                          12345.
+
+      --force             Force compression even when there is an
+                          unexpected value in a header field.
+                          Use with care.
+
+      --strip-relocs=0    Don't strip relocation records.
+      --strip-relocs=1    Strip relocation records. [DEFAULT]
+                          This option only works on executables with base
+                          address greater or equal to 0x400000. Usually the
+                          compressed files becomes smaller, but some files
+                          may become larger. Note that the resulting file will
+                          not work under Windows 3.x (Win32s).
+                          UPX never strips relocations from a DLL
+                          regardless of this option.
+
+      --all-methods       Compress the program several times, using all
+                          available compression methods. This may improve
+                          the compression ratio in some cases, but usually
+                          the default method gives the best results anyway.
+
+      --all-filters       Compress the program several times, using all
+                          available preprocessing filters. This may improve
+                          the compression ratio in some cases, but usually
+                          the default filter gives the best results anyway.
+
+DIAGNOSTICS
+    Exit status is normally 0; if an error occurs, exit status is 1. If a
+    warning occurs, exit status is 2.
+
+    UPX's diagnostics are intended to be self-explanatory.

+=head1 SECURITY CONTEXT
+
+IMPORTANT NOTE: B<UPX> inherits the security context of any files it handles.
+
+This means that packing, unpacking, or even testing or listing a file requires
+the same security considerations as actually executing the file.
+
+Use B<UPX> on trusted files only!
+
+
+
 =head1 DESCRIPTION
 
 B<UPX> is a versatile executable packer with the following features:
 
-  - excellent compression ratio: compresses better than zip/gzip,
+  - secure: as UPX is documented Open Source since many years any relevant
+      Security/Antivirus software is able to peek inside UPX compressed
+      apps to verify them
+
+  - excellent compression ratio: typically compresses better than Zip,
       use UPX to decrease the size of your distribution !
 
-  - very fast decompression: about 10 MiB/sec on an ancient Pentium 133,
-      about 200 MiB/sec on an Athlon XP 2000+.
+  - very fast decompression: more than 500 MB/sec on any reasonably modern
+      machine
 
   - no memory overhead for your compressed executables for most of the
-      supported formats
+      supported formats because of in-place decompression
 
-  - safe: you can list, test and unpack your executables
+  - safe: you can list, test and unpack your executables.
       Also, a checksum of both the compressed and uncompressed file is
       maintained internally.
 
-  - universal: UPX can pack a number of executable formats:
-      * atari/tos
-      * bvmlinuz/386    [bootable Linux kernel]
-      * djgpp2/coff
-      * dos/com
-      * dos/exe
-      * dos/sys
-      * linux/386
-      * linux/elf386
-      * linux/sh386
-      * ps1/exe
-      * rtm32/pe
-      * tmt/adam
-      * vmlinuz/386     [bootable Linux kernel]
-      * vmlinux/386
-      * watcom/le (supporting DOS4G, PMODE/W, DOS32a and CauseWay)
-      * win32/pe (exe and dll)
-      * win64/pe (exe and dll)
-      * arm/pe (exe and dll)
-      * linux/elfamd64
-      * linux/elfppc32
-      * mach/elfppc32
+  - universal: UPX can pack a number of executable formats, including
+      Windows programs and DLLs, macOS apps and Linux executables
 
   - portable: UPX is written in portable endian-neutral C++
 
   - extendable: because of the class layout it's very easy to support
       new executable formats or add new compression algorithms
 
-  - free: UPX can be distributed and used freely. And from version 0.99
-      the full source code of UPX is released under the GNU General Public
-      License (GPL) !
