Use of branches for 3rd party software management

The basic strategy is the following:

• the /main branch is reserved to releases from the 3rd party
• derived objects typically built with without clearmake, but in the vob, are created as elements in a bin branch
• Local configurations and changes are made in side branches

The TOOLS label is thus typically applied over a combination of the three.

This policy is similar to the one used to replicate a vob, when the mastership is at the remote site. We want to be able to easily install new releases as they are available, to compare the changes from the former ones, and to update our own changes.
