Yes it does. So if you're not using it yet, do the below, today, not tomorrow.

If your distro supports it, prepend /usr/lib/ccache/ to your $PATH.
Create symlinks from the names of your favorite cross-compilers
to /usr/bin/ccache, and make sure they are early in your $PATH.

That's it! Enjoy!

when I'm talking to journalists I just say "programmer" or something like that.
