Moving from Makefiles to Rakefiles

I'll be rewriting Hsz's Makefile as a Rakefile during this, and possibly next, week.
Scratch that. I've rewritten part of Hsz's Makefiles--the part that I use to automate the release process, that is packaging the files into an archive--as Rakefiles, but I going to write a very basic Makefile for the Linux version in order to let Linux users install Hsz by simply running

    make DESTDIR=<dir> install
