# repo2gxml.pl
# this converts from the dot repo (.repo) XML file format found in repository.designengineeringlab.org to the GraphSynth 1.9 GXML format.
# 
# because of the faults with the repository data structure or data representation scheme, there is no way for us to recover the functional links, arcs or edges, so for this reason, the output of this program (the gxml) does not include any arcs connecting different components together.
