This directory contains three subdirectories ff -- the ff library ql -- the ql library Doc -- contains the documentation file Typing make should compile the ff library, the ql library and the test program test.f. Executing ./test one should then reproduce the output in test.out. The directory ff is taken from http://www.xs4all.nl/~gjvo/FF.html. The file ffinit_mine.f replaces the original file ff_init.f. One has to adjust here the path (twice) and set it to the location of the the ff library. The makefile in ff has been modified accordingly. For any problems or bug reports send an email to ellis@fnal.gov and g.zanderighi1@physics.ox.ac.uk.
