-- FIXME: what do we want in 1.00 ???
+IMPROVED COMPRESSION RATIO
+==========================
 
-- add NRV2D for dos/exe (use by default when >= 400 kB)
+- experiment with new filters
 
-- implement switch `-m' for method: 1 NRV2B, 2 NRV2D
+- implement filters for linux/elf386
 
-- DLL problem under NT ? is this fixed ???
+- 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
 
 
-PE
+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)
+
+- consider removing "sbb bp,bp" or "or ebp,-1" when not needed
+
+
+FORMAT DJGPP2/COFF
+==================
+
+- handle overlays
+
+- fix default file extension handling when the --coff option is set
+
+
+FORMAT DOS/EXE
+==============
+
+- implement filters
+
+
+FORMAT LINUX/386
+================
+
+- don't mmap() the temporary output file - this seems to improve
+    file io speed
+
+
+FORMAT LINUX/ELF386
+===================
+
+- implement filters
+
+
+FORMAT TMT/ADAM
+===============
+
+- the decompressors are already aligned, no need for an
+    extra alignment
+
+
+FORMAT WATCOM/LE
+================
+
+- 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 WIN32/PE
+===============
+
+- make compressWithFilters() work
+
+- decrease runtime memory overhead
 
 2 - easy - mfx + ml) new switch(es) : do not compress resource types x,y,z
     or resource names a,b,c
+
 3 - medium - ml) rebuild exports
+
 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
+    original section if possible. this could save some virtual memory
-    address space
+    address space.

-LINUX
-=====
-
-4 - ???)
-    - test with AOUT binaries
-    - test with Java binaries
-    - make a compressed program suid. what happens ?
-
-5 - difficult) rewrite the whole stub in assembly
-
-
-SPARC
-=====
-
-3 - easy - ml) finish support - should generate byte-identical versions
-  for all formats (except those which are using Packer::getRandomId())
-
-
-DJGPP2
-======
-
-1 - ???) do we support overlays at all ???
-
-5 - ???) fix file extension handling when the --coff option is set
-
-
-FOR 0.95
-========
-
-- enable automatic dependency tracking
-
-1 - mfx) determine when to use NRV2D, find best c_flags values for
-  NRV2B & NRV2D (see util/runtest.sh)
-
-5 - boring - mfx) Finally fix all screen and UI problems. How boring...
-  Probably should think about the whole system (printf vs. fprintf vs.
-  con_fprintf...)
-
-5 - policy - ml+mfx) Discuss a default C++ style (GNU indent 2.2.3)
-    with Laszlo and use it. Or maybe Artistic Style?
-
-10) Examine why pod2text breaks lines within something like `B<--coff>'.
-    (pod sucks anyway. unfortunately all alternatives as well.)
-
-
-MISC
-====
-
-3 - difficult ml) The first two sentences of the README look too much like
-  those from the aspack docs. Laszlo, could you rewrite this ?
-
-1 - easy - mfx) Check whether the compressed size of the executable is
-  really smaller than the uncompressed
-
-1 - ??? - mfx) Implement a more informational interface.
-    Probably add some global functions in msg.cpp.
-    Should think about the requirements first, i.e. should there be
-    some simple hierarchies (header1, header2, ...) etc. ?
-    Could use the `-v' switch for enabling this (or `-i' ??).
-  - Something like this would be fine:  (with colors :-)
-    [Processing kernel32.dll]
-      [Import]
-        3 DLL.
-        Original size: 12345 bytes.
-        Preprocessed size: 6789 bytes.
-      [Relocations]
-        Original size: 50000 bytes.
-        Preprocessed size: 25000 bytes.
-      [Exports]
-        <warning> exports compressed (try --compress-export=0 if needed)
-      [TLS]
-        Added 56 bytes TLS data.
-        Added 5 fixup records.
-      [Resources]
-        Directory size: 1234 bytes.
-        Resource data size: 100000 bytes.
-        Compressed resources: 8 (99900 bytes).
-        Not compressed resources: 1 (100 bytes).
-
-3 - ???) delete temporary files when something wrong happens
-
-4 - easy - ml) Add a `--486' option to use bswap on the 32-bit formats.
-
-4 - easy - ml) consider removing 'sbb bp,bp' or "or ebp,-1" when not needed
-
-5 - ???) idea: --subfile=xx  compress xx. subfile: we'd need a list_subfiles
-  for this...
-
-
-FIXME: classify

-GOALS FOR 0.90
-==============
-
-- Provide additional NRV2D stubs for all 32-bit formats. Try to do this
-    in a generic way so that we can possibly add more algorithms.
-    Start by adding a `--nrv2d' switch.
-
-FOR 0.90
-========
-
-/ update the output of `--help'
-
-- filters: implement the missing scan() function for f_cto32.
-    Maybe could use this to try to find an optimal filter (e.g.
-    if level >= 9) based on the counts.
-
-- filters: could we have use for a f->firstcall info field ?
-
-TODO
-====
-
-- all formats: more thoroughly test the exe-header in canPack()
-  and throw exceptions when encountering bad values.
-
-- experiment with filters
-
-- for small programs (e.g. < 64k) try an additional algorithm (like
-  the non yet finished NRV2C) to see if it gives better compression ?
-
-/ make checkerg++ work -> test
-
-- fix file extension handling when the --coff option is set
-
-- set up an "official" test suite
-
-- finish documentation
-
