Copy script from Linux added in commit 7683e9e5 (Properly alphabetize MAINTAINERS file) by Linus Torvalds. > This adds a perl script to actually parse the MAINTAINERS file, clean > up some whitespace in it, warn about errors in it, and then properly > sort the end result. > > My perl-fu is atrocious, so the script has basically been created by > randomly putting various characters in a pile, mixing them around, and > then looking it the end result does anything interesting when used as > a perl script.
