symbal (SYmmetry, BAses, and Lexicography) Release 0.1

This is an extremely preliminary release of the symbal package, for
those of you that might want to duplicate the experiments in 

 D. Bremner, M. D. Sikiric, and A. Schrmann. Polyhedral
 representation conversion up to symmetries. January
 2007.  http://www.arxiv.org/abs/math.MG/0702239.

You will need to 

1) Edit Makefile to point to your main gap directory (whereever sysinfo.gap
lives)

2) make

3) add the current directory as a gap root directory using "-l"


Shortcomings:

1) there is no documentation :-(, but many examples :-)

2) finding an initial basis in the symbolic orbitwise perturbation has 
	not been implemented.  You can cheat by taking a basis from the 
	numerical orbitwise perturbation as your initial basis.

3) many examples have the root directory hardcoded in the top of the file.
	you will have to change to get them to run

License: GPL v2, see COPYING. For your convenience, this tarball
includes a copy of lrslib and nauty. Note that the nauty license
forbids "non-trivial military applications".
