The original configure gunk is a pile of SHIT for what's needed to
build reasonable releases, and it does install files in / if emacs
can't be found at all!!!
Split into three packages, depending onto the emacs flavor wanted,
none by default.
Porters: please make sure you use bsd.port.mk 1.75 or later when
updating ports. That version of the makefile adds all sums. Previous
versions of the makefile will still work for people installing ports.
