The Minstrel's Song is copyright 1998, by Jonathan Hayward. See the file lib/copyrigh.txt for details.
To compile and run this game, go into the directory src, edit the file "tms.h" according to the comments that are contained in, and use make.
More specifically, it needs a certain lib directory, where all of the files in "lib" are stored. /usr/local/lib/tms is reccommended. Once you have created that directory and moved all of the files to it (be sure that book8.txt is writeable by everybody -- it is more or less the high score file), set LIB_DIR in tms.h to that directory, with a trailing slash -- ie. change appropriate line to say
#define LIB_DIR "/usr/local/lib/tms/"
(or whatever you have put for your lib directory.)
Security note: It is strongly discouraged to install TMS as a SetUID binary; the game is not designed to have special priveleges.
