the program website 2009, March 25...single file compressor based on fast ROLZ+ARI compression. It supports the BMP,EXE,WAVE compression with filters. At moment support files > 4GB.
2009 March 22. the author submitted the following configurations: 'Default, -m1 -s1 -b1, -m1 -s1 -b5, -m2 -s4 -b5, -m1 -s7 -b5, -m2 -s7 -b5'. 0.99b4 supports larger values for b-switch, so we use -b8 instead of -b5 (previously the maximum).
Updated configurations were sent by the author in 2009 September 28 for 0.99b5, 2010 February 22 for 0.99b7 and 2010 March 1 for 0.99b8.
The program uses the archiver template to implement archiver features.
(Have info that should be added here? E-mail.)
v0.92 and 0.93b disqualified: programs display copyright information and quit. No output is produced and no error message is given. v0.93c: '-m1 -s7 -b5' and '-m2 -s7 -b5' crash on decompressing OS1.
0.99b1 tested with TAR because the archiver feature works in an unusual way with absolute path required as a parameter.
0.99b5 '-m0 -c1 -b8' crashes when compressing Application1.
0.99b7 most configurations do not compress anything and no error message is given.
0.99b8 configurations print out 'No memory.' with -b8 hence we use -b7 instead.
