Log Message:
New package to inspect squid caches and extract data from them.
Patched for pkgsrc pathnames (default location of squid config file),
and for NetBSD; probably needs help for other pkgsrc platforms but not
marked ONLY_ because there's no good reason it can't be made to work.

While not useful to run this w/o squid, the package does not depend on
it because it can be built and installed without it.

The package and binary are named squidpurge because purge seems too
likely to conflict and squid users are more likely to notice it this way.
