 +====== CCache ======
 +Using ccache can speed up rebuilds a lot. When set up, it caches the binary objects as applications are built, and later it copies those objects back, instead of having to recompile them.
 +
 +Slackware comes with ccache.
 +
 +To start using it, get root and:\\
 +cd /​usr/​local/​bin\\
 +
 +ln -s /​usr/​bin/​ccache cc\\
 +ln -s /​usr/​bin/​ccache c++\\
 +ln -s /​usr/​bin/​ccache gcc\\
 +ln -s /​usr/​bin/​ccache g++\\
 +
 +To set a max size for the cache, use EG:\\
 +ccache -M 5G\\
 +That sets a max size of 5GB in ~/.ccache\\
 +You obviously need to set it for your needs and available space.\\
 +
 +To see some info about ccache, do:\\
 +ccache -s\\
 +
 +To temporarily turn it off:\\
 +CCACHE_DISABLE=1\\
 +can be put in a SlackBuild or exported in the shell.\\
 +If that fails to work then just move the symlinks out of /​usr/​local/​bin
 +
 +and don't forget to read the man page.
