[Tuxmath-devel] install updates

[William K. <nb...@so...>]

I've added an "install" target to the Makefile.
By default, it copies the data files to "/usr/share/tuxmath/"
and copies the executable to "/usr/local/bin/"

These can be overridden when you first run "make" (and then when you
run "make install", you need to specify them again), by giving "make"
values for "DATA_PREFIX" and "BIN_PREFIX".

Also, the "INSTALL.txt" file has been fleshed out quite a bit.
It includes info. on requirements (hardware, software, etc.) and
where to get libSDL.

It finally includes compilation and installation instructions for
Linux/Unix.


Also, "SDL_mixer" is no optional.  Run "make nosound" to compile it
without "#include <SDL_mixer.h>" or any references to mixer stuff,
and it won't try to link with "libSDL_mixer.so". :)


Go 'cvs update' now to see! :)
