-#! /usr/bin/env python3

-# Fix Python source files to avoid using
-# def method(self, (arg1, ..., argn)):
-# instead of the more rational
-# def method(self, arg1, ..., argn):
-#
-# Command line arguments are files or directories to be processed.
-# Directories are searched recursively for files whose name looks
-# like a python module.
-# Symbolic links are always ignored (except as explicit directory
-# arguments). Of course, the original file is kept as a back-up
-# (with a "~" attached to its name).
-# It complains about binaries (files containing null bytes)
-# and about files that are ostensibly not Python files: if the first
-# line starts with '#!' and does not contain the string 'python'.
-#
-# Changes made are reported to stdout in a diff-like format.
-#
-# Undoubtedly you can do this using find and sed or perl, but this is
-# a nice example of Python code that recurses down a directory tree
-# and uses regular expressions. Also note several subtleties like
-# preserving the file's mode and avoiding to even write a temp file
-# when no changes are needed for a file.
-#
-# NB: by changing only the function fixline() you can turn this
-# into a program for a different change to Python programs...
