Files in a project may contain instances of keywords that (in effect)
prcs checkin will replace with certain information.
Conceptually, upon checkin, each keyword instance in every file
of the project (not just
those listed in the checkin subcommand)
is updated as described below with the value of its
keyword in the new project version. As a performance consideration,
however, this is implemented in such a way that partial checkins only
have to examine the files that are listed in the checkin subcommand (see Keywords and File Identifiers).
There are two formre files, files generated by TeX, Postscript (.ps) files that occur in subdirectory doc, Emacs backup files, and the executable file a.out:
(Populate-Ignore ("\\.o$" "\\.a$" "~$" "^a.out$" "^core$"
"\\.dvi$" "\\.aux$" "\\.log"
"^doc/.*\\.ps"))
