32 | Help=' |
33 | Generate ChangeLog entries from RCS files (perhaps in a CVS repository) | |
34 | and the ChangeLog file (if any). An RCS file typically has a name | |
35 | ending in ",v", and represents the entire history of a file that is | |
36 | under revision control. The ChangeLog file logs entries for changes, | |
37 | in reverse chronological order. | |

442a2160 PE |
39 | Generate entries for changes entered into RCS (or CVS) more recently |
40 | than the newest existing entry in the ChangeLog file. You can then | |
41 | edit these entries by hand, and prepend them to the ChangeLog file. | |
42 | ||
43 | Output the resulting ChangeLog entries to standard output. | |
44 | Each entry looks something like this: | |

48 | * rcs2log (Help): Clarify wording of the usage message. | |
49 | Problem reported by Alan Mackenzie in | |
50 | <http://mail.gnu.org/archive/html/bug-gnu-emacs/2004-04/msg00188.html>. | |
51 | ||
52 | ChangeLog entries contain the current date, full name, email address | |
53 | including hostname, the name of the affected file, and commentary. | |
54 | RCS and CVS logs lack full names and email addresses, so they are | |
55 | inferred from login names using a heuristic that can be overridden | |
56 | via the -u option. | |
57 | ||
58 | Ignore log entries that start with "#". | |
59 | Clump together log entries that start with "{topic} ", | |
60 | where "topic" contains neither white space nor "}". | |
61 | ||
62 | If no FILE is specified, use all files under the working directory | |
63 | that are maintained under version control. | |

65 | Options: |
66 | ||
442a2160 | 67 | -c FILE Output ChangeLog entries for FILE (default ChangeLog). |
daecaf5d GM |
68 | -h HOSTNAME Use HOSTNAME in change log entries (default current host). |
69 | -i INDENT Indent change log lines by INDENT spaces (default 8). | |
70 | -l LENGTH Try to limit log lines to LENGTH characters (default 79). | |
442a2160 | 71 | -L FILE Use FILE (same format as "rlog") for source of logs. |
daecaf5d | 72 | -R If no FILEs are given and RCS is used, recurse through working directory. |
442a2160 | 73 | -r OPTION Pass OPTION to subsidiary command (either "rlog" or "cvs -q log"). |
daecaf5d | 74 | -t TABWIDTH Tab stops are every TABWIDTH characters (default 8). |
442a2160 | 75 | -u "LOGIN<tab>FULLNAME<tab>EMAILADDR" LOGIN has FULLNAME and EMAILADDR. |
daecaf5d GM |
76 | -v Append RCS revision to file names in log lines. |
77 | --help Output help. | |
78 | --version Output version number. | |
