# This is a GAP demonstration file. 
# To run a demonstration enter the following:
# gap> LogTo(); # (if you are logging to a file)
# gap> ReadLib("demo.g");
# gap> Demonstration("omdemo.g");
# (probably you will need the full path in the last 
# command). Then you may press <Enter> to go to the 
# next step or press <q> to terminate demonstration
#

# This tests reads OM objects from scscp/tst/omdemo.om file
# It does not use network connection and only test OMGetObjectWithAttributes
