[12] I need source for the winners of the Dr Dobbs compression contest

The source of the top 6 programs of the Feb 91 Dr Dobbs data compression
contest are available by ftp on
  ftp://ftp.simtel.net/pub/simtelnet/msdos/compress/ddjcompr.zip
  ftp://garbo.uwasa.fi/pc/source/ddjcompr.zip

The sources are in MSDOS end-of-line format, one directory per
program.  Unix or VMS users, use "unzip -a ddjcompr" to get correct
end-of-lines (add -d to recreate the directory structure if you are
using an obsolete version of unzip such as 4.1). Three of the 6
programs are not portable and only run on MSDOS. compact and urban
work on Unix, sixpack only requires minor modifications.
