| Usage: $ME [OPTIONS] [ARGS] |
| |
| Convert git log output to ChangeLog format. If present, any ARGS |
| are passed to "git log". To avoid ARGS being parsed as options to |
| $ME, they may be preceded by '--'. |
| |
| OPTIONS: |
| |
| --since=DATE convert only the logs since DATE; |
| the default is to convert all log entries. |
| --format=FMT set format string for commit subject and body; |
| see 'man git-log' for the list of format metacharacters; |
| the default is '%s%n%b%n' |
| --append-dot append a dot to the first line of each commit message if |
| there is no other punctuation or blank at the end. |
| |
| --help display this help and exit |
| --version output version information and exit |
| |
| EXAMPLE: |
| |
| $ME --since=2008-01-01 > ChangeLog |
| $ME -- -n 5 foo > last-5-commits-to-branch-foo |
