[ccache] ccache-like tool

[David Boyce]

I recently released a GPL tool which is, in part, an alternative to
ccache and thought I'd drop a line to this list for anyone interested.
The front page is at http://audited-objects.sourceforge.net/ and a
comparison with ccache is at
http://audited-objects.sourceforge.net/html/man/ao-ccache.html. As a
matter of fact I haven't used ccache seriously in quite a few years,
since I've been developing my own tool, so I'd appreciate any
corrections to the comparison document.
