[3] Distributed under the terms of the GNU General Public License, distcc is free software.

distcc is designed to speed up compilation by taking advantage of unused processing power on other computers.

distcc was an option for distributed builds in versions of Apple's Xcode development suite prior to 4.3, but has been removed.

Goma is a similar tool made by Google to replace distcc & ccache in compiling chromium.

ccache is another tool aimed to reduce the compilation time by caching the output from the same input source files.
