=item B<pb_env_init>

This function setup the environment for project-builder.
The first parameter is the project if given on the command line.
The second parameter is a flag indicating whether we should setup up the pbconf environment or not.
The third parameter is the action passed to pb.
It sets up environement variables (PBETC, PBPROJ, PBDEFDIR, PBBUILDDIR, PBROOTDIR, PBDESTDIR, PBCONFDIR, PBPROJVER)
