Comment (by ppurka):
You can of course have only one ccache dir. In that case, simply define
the environment variable `CCACHE_DIR` in your shell rc file. Then
everything will use that directory. The default is set for those people
who don't bother with setting up ccache variables.
{{{
~» sage --sh
Starting subshell with Sage environment variables set. Don't forget
to exit when you are done. Beware:
* Do not do anything with other copies of Sage on your system.
* Do not use this for installing Sage packages using "sage -i" or for
running "make" at Sage's root directory. These should be done
outside the Sage shell.
Bypassing shell configuration files...
