3 | # This script accepts any number of file arguments and checks them into RCS. |
4 | # | |
5 | # Arguments which are detectably either RCS masters (with names ending in ,v) | |
6 | # or Emacs version files (with names of the form foo.~<number>~) are ignored. | |
7 | # For each file foo, the script looks for Emacs version files related to it. | |
8 | # These files are checked in as deltas, oldest first, so that the contents of | |
9 | # the file itself becomes the latest revision in the master. | |
10 | # | |
11 | # The first line of each file is used as its description text. The file itself | |
12 | # is not deleted, as under VC with vc-keep-workfiles at its default of t, but | |
13 | # all the version files are. | |
14 | # | |
15 | # If an argument file is already version-controlled under RCS, any version | |
16 | # files are added to the list of deltas and deleted, and then the workfile | |
17 | # is checked in again as the latest version. This is probably not quite | |
18 | # what was wanted, and is the main reason VC doesn't simply call this to | |
19 | # do checkins. | |
20 | # | |
21 | # This script is intended to be used to convert files with an old-Emacs-style | |
22 | # version history for use with VC (the Emacs 19 version-control interface), | |
23 | # which likes to use RCS as its back end. It was written by Paul Eggert | |
d2b64180 | 24 | # and revised/documented for use with VC by Eric S. Raymond, Mar 19 1993. |
