- """(Ostensibly) fix copyright notices in files.
-
- Actually, this sript will simply replace a block of text in a file from one
- string to another. It will only do this once though, i.e. not globally
- throughout the file. It writes a backup file and then does an os.rename()
- dance for atomicity.
-
- Usage: fixnotices.py [options] [filenames]
- Options:
- -h / --help
- Print this message and exit
-
- --oldnotice=file
- Use the notice in the file as the old (to be replaced) string, instead
- of the hard coded value in the script.
-
- --newnotice=file
- Use the notice in the file as the new (replacement) string, instead of
- the hard coded value in the script.
-
- --dry-run
- Don't actually make the changes, but print out the list of files that
- would change. When used with -v, a status will be printed for every
- file.
-
- -v / --verbose
- Print a message for every file looked at, indicating whether the file
- is changed or not.
