#  RAPPTURE LAUNCHER
#
#  This script is invoked by the "rappture" command.  It parses
#  various input options and selects the proper main program to
#  run depending on the function (build tool, run tool, tester, etc.).
#
#  RUN AS FOLLOWS:
#    rappture ?-run? ?-tool <toolfile>?
#    rappture -builder ?-tool <toolfile>?
#    rappture -tester ?-tool <toolfile>? ?-testdir <directory>?
#
#  The default option is "-run", which brings up the GUI used to
#  run the tool.  If the <toolfile> is not specified, it defaults
#  to "tool.xml" in the current working directory.

#	blt::bgexec.  It doesn't try to redirect stderr into a file.
