"""(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.
