NOTE: The gzip code was removed from depot so as to not require the
GNU Public License to cover the entire code base. The change has also
allowed other compression schemes to be used.

configure will try to use gzip/gunzip by default. If those programs do
not exist, then compress/uncompress will be used. If that fails then
the compression method will be compiled in as 'cat' to allow for the
introduction of a compression program at a later date.

gzip can be explicitly specified by running configure as
	configure -with-gzip=PATH

compress can be specified encoded by running configure as
	configure -with-compress=PATH

In both of these examples the string PATH will be used as the path to
both the compression and decompression programs. The arguments to gzip
and compress are 'standard' so those will not need to be specified. In
the event that they change, see the next below on how to override the
default choices. 

Alternate forms of compression can be specified by setting the
environment variables DEPOT_COMPRESS and DEPOT_DECOMPRESS before
running configure. DEPOT_COMPRESS should be set to be compression
program (please give the full path and any arguments necessary to send
the output to stdout and read the input from stdin). The same applies
to DEPOT_DECOMPRESS.  For example, in the compress case
	DEPOT_COMPRESS	 would be set to "compress -c"
and	DEPOT_DECOMPRESS would be set to "uncompress -c"

These environment variables will also be checked during the depot
run. 

Be aware that if you run depot inside a setuid wrapper, be sure to
clobber these environment variables!

There is no support for auto detecting the compression method used so
don't try to mix and match compression methods as it just won't work.
