#  This script rebuilds sources not kept in the GIT repository.

#  AutoGen before building AutoGen.

#  "make" will invoke this file with the name of the desired output
#  as an argument.  We do this here rather than in the make file
#  because some of the rules are complex and we don't want to
#  deal with the dual update problem.
