Generate ChangeLog entries from RCS files (perhaps in a CVS repository)
|
||
and the ChangeLog file (if any). An RCS file typically has a name
|
||
ending in ",v", and represents the entire history of a file that is
|
||
under revision control. The ChangeLog file logs entries for changes,
|
||
in reverse chronological order.
|
||
|
||
Generate entries for changes entered into RCS (or CVS) more recently
|
||
than the newest existing entry in the ChangeLog file. You can then
|
||
edit these entries by hand, and prepend them to the ChangeLog file.
|
||
|
||
Output the resulting ChangeLog entries to standard output.
|
||
Each entry looks something like this:

* rcs2log (Help): Clarify wording of the usage message.
|
||
Problem reported by Alan Mackenzie in
|
||
<https://mail.gnu.org/archive/html/bug-gnu-emacs/2004-04/msg00188.html>.
|
||
|
||
ChangeLog entries contain the current date, full name, email address
|
||
including hostname, the name of the affected file, and commentary.
|
||
RCS and CVS logs lack full names and email addresses, so they are
|
||
inferred from login names using a heuristic that can be overridden
|
||
via the -u option.
|
||
|
||
Ignore log entries that start with "#".
|
||
Clump together log entries that start with "{topic} ",
|
||
where "topic" contains neither white space nor "}".
|
||
|
||
If no FILE is specified, use all files under the working directory
|
||
that are maintained under version control.
|
||
|
||
Options:
|
||
|
||
-c FILE Output ChangeLog entries for FILE (default ChangeLog).
|
||
-h HOSTNAME Use HOSTNAME in change log entries (default current host).
|
||
-i INDENT Indent change log lines by INDENT spaces (default 8).
|
||
-l LENGTH Try to limit log lines to LENGTH characters (default 79).
|
||
-L FILE Use FILE (same format as "rlog") for source of logs.
|
||
-R If no FILEs are given and RCS is used, recurse through working directory.
|
||
-r OPTION Pass OPTION to subsidiary command (either "rlog" or "cvs -q log").
|
||
-t TABWIDTH Tab stops are every TABWIDTH characters (default 8).
|
||
-u "LOGIN<tab>FULLNAME<tab>EMAILADDR" LOGIN has FULLNAME and EMAILADDR.
|
||
-v Append RCS revision to file names in log lines.
|
||
--help Output help.
|
||
--version Output version number.
