To run the tests, first do a "make all tests" from the unix/ directory. If all goes well, type "make install" (the library files must be installed before the tests can run successfully). Then enter unix/test (this directory) and type "run_all_tests". Test output will be placed in the test/out directory. You should check up on any .diff files which are placed there; they indicate a mismatch between the test log and the pre-generated log. - tril@igs.net
