6 | # The basic idea is to aggregate CVS check-ins into related changes. | |
7 | # Fortunately, "cvsps" does that for us; all we have to do is to parse | |
8 | # its output. | |
9 | # | |
10 | # Checking out the files is done by a single long-running CVS connection | |
11 | # / server process. | |
12 | # | |
13 | # The head revision is on branch "origin" by default. | |
14 | # You can change that with the '-o' option. | |
