ARJ 2.00 is available on simtel under pd1:<msdos.arc-lbr>arj200.exe.
I ran some crude tests using 11 binary files and 11 text files.  Here
are my results.  All times in seconds of course ;-)

Binary data - 11 misc. EXE files (358,783 bytes).

           Compression time    Compressed size    Decompression time
LHa 2.12       1:44.89            244,226              42.74
ARJ 2.00       1:27.74            243,498              44.50
PKZIP 1.1      1:00.05            251,433              22.25

Text data - 11 misc straight ASCII files (247,669 bytes).

           Compression time    Compressed size    Decompression time
LHa 2.12       1:15.98             88,193              24.12
ARJ 2.00       1:00.54             85,859              26.37
PKZIP 1.1        48.84             92,057              17.91

Considering ARJ 1.10 sucked (flames >/dev/null), this is a tremendous
improvement.  Phil Katz is the only one that hasn't released a new
version of ZIP, but I'm sure that's in the works.
