| Subject | [PATCH] parse-maintainers: Add ability to specify filenames |
| Message-ID | <ucqtH-1Fl-9@gated-at.bofh.it> |
parse-maintainers.pl is convenient, but currently hard-code the
filenames that are used.
Allow user-specified filenames to simplify the use of the script.
Miscellanea:
o Change the file permissions to 755 to the script is executable

Hey Linus.
Andrew picked this up, but his quilt based tools to not
keep the file permission change.
Could you pick this up instead please?
It could be useful if/when the MAINTAINERS file is split
and when the individual files need to be realphabetized.
Thanks.
