Usage:

   p4pcm.pl [-d "proxy cache dir"] [-tlow <low_threshold>] [-thigh <high_threshold>] [-n]
or
   p4pcm.pl -h

This utility removes files in the proxy cache if the amount of free disk space
falls below the low threshold (default 10GB).  It removes files (oldest first)
until the high threshold is (default 20GB) is reached. Specify the thresholds
in kilobyte units (kb).

The '-d "proxy cache dir"' argument is required unless $P4PCACHE is defined,
in which case it is used.

The log is $LOGS/p4pcm.log if $LOGS is defined, else p4pcm.log in the current
directory.

Use '-n' to show what files would be removed.
