The author has tried his best to produce correct and useful programs, in order to help promote computer science research, but no warranty of any kind should be assumed.

Then, on a UNIX-like system, edit the Makefile as instructed there, and "make install". Complete instructions will appear in a book by D. E. Knuth entitled The Stanford GraphBase: A Platform for Combinatorial Algorithms. Note: The system is presently in alpha-test state, meaning that everything appears to work on at least one system; but experience on a broad range of computers is lacking. Please communicate all suggested improvements to firstname.lastname@example.org, with subject line "GraphBase Alpha Test".
