Parallel building
clearmake includes support for parallel building (concurrent
execution of a set of build scripts on one or most hosts).
A command option
specifies the number of hosts to use; host names to use are read from a build hosts file (see
the following figure).
Figure 1. Parallel building

For example, you can perform a three-way build, all of whose processes execute on a single multiprocessor server; an overnight build can be distributed across all the workstations in the local network.
