| 25 | # Arguments which are detectably either RCS masters (with names ending in ,v) |
| 26 | # or Emacs version files (with names of the form foo.~<number>~) are ignored. |
| 27 | # For each file foo, the script looks for Emacs version files related to it. |
| 28 | # These files are checked in as deltas, oldest first, so that the contents of |
| 29 | # the file itself becomes the latest revision in the master. |
| 30 | # |
| 31 | # The first line of each file is used as its description text. The file itself |
| 32 | # is not deleted, as under VC with vc-keep-workfiles at its default of t, but |
| 33 | # all the version files are. |
| 34 | # |
| 35 | # If an argument file is already version-controlled under RCS, any version |
| 36 | # files are added to the list of deltas and deleted, and then the workfile |
| 37 | # is checked in again as the latest version. This is probably not quite |
| 38 | # what was wanted, and is the main reason VC doesn't simply call this to |
| 39 | # do checkins. |
| 40 | # |
| 41 | # This script is intended to be used to convert files with an old-Emacs-style |
| 42 | # version history for use with VC (the Emacs 19 version-control interface), |
| 43 | # which likes to use RCS as its back end. It was written by Paul Eggert |
| 44 | # and revised/documented for use with VC by Eric S. Raymond, Mar 19 1993. |
