A few days ago I sent in some enhancements to makewhatis.{sh,sed}
to add support for gzipped files (and cgd added compressed files
support.)

Marc Boschma (marcb@werj.com.au) provided me with the following
enhancements to <bsd.man.mk> to allow autocompression of manual
pages as they get installed. I cleaned up the stuff a bit, and
made it more generic (rather than just being hardcoded to gzip.)

To kick-in compression using gzip, just define  MAN_COMPRESS
in your environment.

If you want to use an alternative compression scheme,
set MAN_COMPRESS to the command to use, and MAN_COMPRESS_SUFFIX
to the suffix that $MAN_COMPRESS generates.

Note that in its current form, it won't remove old versions of
compressed manuals if you only use the compression for a short
while - you'll have to remove them by hand, or enhance the
dependancies.


So, here's the patch (joint effort between myself & Marc.)

PS: could someone update my email address in the doc/CHANGES
from whatever it is (probably zak@rmit.edu.au or s902113@minyos...
to lm@rmit.edu.au. Thanks.)
