-
-IMPORTANT PROBLEMS THAT SHOULD BE FIXED SOON:
-
-- [None]
-
-
-OTHER:
-
-- docs: convert docs from upx.pod to use AsciiDoc
-
-- check all <const_cast> to make sure they are not invalid
-
-- throwNotCompressible() is not a real error, so make the output nicer
-  (info: bla bla). Also ui.cpp (total_*).
-
-
------------------------------------------------------------------------
-
-
-IMPROVED COMPRESSION RATIO
-==========================
-
-- experiment with new filters
-
-- implement filters for dos/exe
-
-- filters: could we exploit a f->firstcall info field ?
-
-- for small programs (e.g. < 64k), try an additional algorithm
-  to see if it gives better compression
-
-
-ALL FORMATS
-===========
-
-- more thoroughly test the exe-header in canPack()
-  and throw exceptions when encountering bad values.
-
-- implement `--cpu=486' option to use bswap on the 32-bit formats
-    (if cpu >= 486)
-
-
-FORMAT DJGPP2/COFF
-==================
-
-- handle overlays
-
-- fix default file extension handling when the --coff option is set
-
-
-FORMAT DOS/EXE
-==============
-
-- implement filters
-
-- add a check so that we don't pack djgpp1 binaries
-
-
-FORMAT LINUX/386
-================
-
-- don't mmap() the temporary output file - this seems to improve
-    file io speed
-
-
-FORMAT TMT/ADAM
-===============
-
-- the decompressors are already aligned, no need for an
-    extra alignment
-
-
-FORMAT WATCOM/LE
-================
-
-- handle files without relocations
-
-- the decompressors are already aligned, no need for an
-    extra alignment
-
-- fix default file extension handling when the --le option is set
-
-- handle holes in the file
-
-
-FORMAT WIN16/NE
-===============
-
-- implement readFileHeader() to correctly identify a win16/ne
-  executable, so that the call for contribution will get thrown
-
-
-FORMAT WIN32/PE
-===============
-
-- fix the section alignment with the Intel compiler
-
-- decrease runtime memory overhead
-
-3 - difficult) don't compress the BSS section and other holes.
-
-4 - medium - ml) fix when objectalign < 0x1000
-
-4 - easy - ml) put the original offset of moved resources somewhere into
-    the res.dir. (if it's safe to do)
-
-4 - ??? - ml) fix FIXMEs
-
-5 - medium - ml) try to put the preprocessed imports & relocs back to their
-    original section if possible. this could save some virtual memory
-    address space.
