#! /usr/bin/python2.7 """(Ostensibly) fix copyright notices in files. Actually, this script 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.
