+# 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...
