@aizuchi @mcc At my first job out of college we used RCS over NFS even though CVS existed by then, because the CTO of the company was Very Smart and had a belief that CVS was troublesome because he didn't want to learn how to resolve conflicts.

The repository also used strict locking and pretty much all of the functionality was in one gigantic .c file that people would always forget to checkin/unlock before going on vacation.
