ccache

Ccache is a compiler cache that speeds up rebuilding of packages. It helps over normal incremental compilation by saving the object files in its cache even through a make clean.

Setup on Ubuntu/Debian

• Install the package: sudo apt-get install ccache
• Add ccache symlinks to your path by appending the following to ~/.bashrc (or equivalent for your shell)
  

  if [ -d /usr/lib/ccache/ ] ; then
      PATH="/usr/lib/ccache:$PATH"
