+### Commentary:
+
+## Forward emails from the emacs-elpa-diffs mailing list to the
+## maintainer(s) of the modified files.
+
+## Example usage from procmail (all arguments are compulsory):
+
+## :0c
+## * address@hidden
+## | forward-diffs.py -m maintfile -l logfile -s sender
+
+## where 
+
+## sender = your email address
+## logfile = file to write log to (you might want to rotate/compress/examine 
it)
+## maintfile = file listing packages and their maintainers, with format:
+##
+## package1   email1
+## package2   email2,email3
