说明
RCS (Revision Control System) manages multiple revisions of files, providing version control for individual files. It automates storing, retrieving, logging, and merging revisions, making it useful for source code, documentation, and configuration files. The workflow centers on ci (check-in) and co (check-out). Check-in stores a new revision and removes the working file by default. Check-out retrieves a revision; use -l to lock the file for exclusive editing. RCS stores revisions efficiently using reverse deltas—the latest revision is stored complete, while older revisions are stored as differences. This makes retrieving the current version fast. Revisions are numbered hierarchically (1.1, 1.2, 1.3, etc.). The first number is the release, the second is the level. Branches create additional number fields (1.2.1.1).
