U61 uses gnu autoconf, the scripts are not perfect yet, but should
work OK to compile and try the project.

You *need* to have ClanLib to compile U61
ClanLib 0.4.4 seems to work OK for U61.
You'll also need to have Lua and MikMod installed,
and compile the clanLua and clanMikMod shared library.

Usefull URLs:
clanlib : http://clanlib.org
lua     : http://www.tecgraf.puc-rio.br
mikmod  : http://mikmod.darkorb.net

Otherwise, just type:
$ autoconf
$ ./configure
$ make
# make install (must be launched as root)
$ ./u61

The install script is not clean yet, and probably won't be until
I get a truely stable and nearly final version of the game...
