Updating with the import command

When a new release of the source arrives, you import it into the repository with the same import command that you used to set up the repository in the first place. The only difference is that you specify a different release tag this time.

$ tar xfz wdiff-0.05.tar.gz
$ cd wdiff-0.05
$ cvs import -m "Import of FSF v. 0.05" fsf/wdiff FSF_DIST WDIFF_0_05

For files that have not been modified locally, the newly created revision becomes the head revision. If you have made local changes, import will warn you that you must merge the changes into the main trunk, and tell you to use `checkout -j' to do so.

$ cvs checkout -jFSF_DIST:yesterday -jFSF_DIST wdiff

The above command will check out the latest revision of `wdiff', merging the changes made on the vendor branch `FSF_DIST' since yesterday into the working copy. If any conflicts arise during the merge they should be resolved in the normal way (see section Conflicts example). Then, the modified files may be committed.

Using a date, as suggested above, assumes that you do not import more than one release of a product per day. If you do, you can always use something like this instead:

$ cvs checkout -jWDIFF_0_04 -jWDIFF_0_05 wdiff

In this case, the two above commands are equivalent.
