In this case, we were updating NCO 4.2.3 to GMAO-Baselibs-3_3_0. So, the "internal" tag we went to was 3_3_1. In a temporary directory (say, NewBaselibs) you checkout Baselibs and tag relative so you know where you started from. You also make sure the tag you're making doesn't exist:

Note that this command provides helpful information on how to merge this package. You'll want to make a note of the previous release tag. The best way to find this out is via tkcvs, in my opinion.

Note in this case that no conflicts were found. If there were conflicts, you should resolve them. When in doubt, I suggest always using '''only''' what the new package contained. The only exceptions might be in Makefiles or other files that might have been edited by Denis or other maintainers to get it to build with the other Baselibs. But, if at all possible, go with the stock library.
