Icecream is a distributed compile system. It allows parallel compiling by distributing the compile jobs to several nodes of a compile network running the icecc daemon. The icecc scheduler routes the jobs and provides status and statistics information to the icecc monitor. Each compile node can accept one or more compile jobs depending on the number of processors and the settings of the daemon. Link jobs and other jobs which cannot be distributed are executed locally on the node where the compilation is started. Note that upon installation of the resulting package, all your software will be compiled by icecream by default. For information on how to use icecream in combination with ccache see http://old-en.opensuse.org/Icecream#How_to_combine_icecream_with_ccache librsync is an optional dependency.
