  31 Generate ChangeLog entries from RCS files (perhaps in a CVS repository)
  32 and the ChangeLog file (if any).  An RCS file typically has a name
  33 ending in ",v", and represents the entire history of a file that is
  34 under revision control.  The ChangeLog file logs entries for changes,
  35 in reverse chronological order.
  36
  37 Generate entries for changes entered into RCS (or CVS) more recently
  38 than the newest existing entry in the ChangeLog file.  You can then
  39 edit these entries by hand, and prepend them to the ChangeLog file.
  40
  41 Output the resulting ChangeLog entries to standard output.
  42 Each entry looks something like this:

  46         * rcs2log (Help): Clarify wording of the usage message.
  47         Problem reported by Alan Mackenzie in
  48         <http://mail.gnu.org/archive/html/bug-gnu-emacs/2004-04/msg00188.html>.
  49
  50 ChangeLog entries contain the current date, full name, email address
  51 including hostname, the name of the affected file, and commentary.
  52 RCS and CVS logs lack full names and email addresses, so they are
  53 inferred from login names using a heuristic that can be overridden
  54 via the -u option.
  55
  56 Ignore log entries that start with "#".
  57 Clump together log entries that start with "{topic} ",
  58 where "topic" contains neither white space nor "}".
  59
  60 If no FILE is specified, use all files under the working directory
  61 that are maintained under version control.
  62
  63 Options:
  64
  65   -c FILE  Output ChangeLog entries for FILE (default ChangeLog).
  66   -h HOSTNAME  Use HOSTNAME in change log entries (default current host).
  67   -i INDENT  Indent change log lines by INDENT spaces (default 8).
  68   -l LENGTH  Try to limit log lines to LENGTH characters (default 79).
  69   -L FILE  Use FILE (same format as "rlog") for source of logs.
  70   -R  If no FILEs are given and RCS is used, recurse through working directory.
  71   -r OPTION  Pass OPTION to subsidiary command (either "rlog" or "cvs -q log").
  72   -t TABWIDTH  Tab stops are every TABWIDTH characters (default 8).
  73   -u "LOGIN<tab>FULLNAME<tab>EMAILADDR"  LOGIN has FULLNAME and EMAILADDR.
  74   -v  Append RCS revision to file names in log lines.
  75   --help  Output help.
  76   --version  Output version number.
