This version incorporates plain distcc as well as an enhancement
called pump mode or distcc-pump.<BR>
<P>
For each job, distcc in plain mode sends the complete preprocessed
source code and compiler arguments across the network from the
client to a compilation server.  In pump mode, distcc sends the
source code and recursively included header files (excluding those

and compilation can take place on the compilation servers. This
