Subject: setup: rename GNUmakefile to Makefile
X-Git-Url: https://git.rkrishnan.org/(%5B%5E?a=commitdiff_plain;h=d6c66f99c01efd3edbd5b177e7348a159d155c2e;p=tahoe-lafs%2Ftahoe-lafs.git

setup: rename GNUmakefile to Makefile
It's evil and wrong to call something a "Makefile" when it contains code that can't be interpreted by POSIX make and requires GNU make.
But everyone else is doing it.  ;-)
