fixnotice.py
#! /usr/bin/env python
"""(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.
