# available, then we have to just use the existing diagram.  Second, different
# "dot" versions produce slightly different output for the same input, but we
# don't want to gratuitously change vswitch.pic if someone tweaks the schema in
# some minor way that doesn't affect the table structure.  To avoid that we
# store a checksum of vswitch.gv in vswitch.pic and only regenerate vswitch.pic
# if vswitch.gv actually changes.
