$DECK
This is a test script wrapper for the run_make_tests.pl script.

This wrapper makes sure that the DCL symbols and logical names needed to
run the perl script are in place.

The test wrapper currently requires that the DCL symbols be global symbols.
Those symbols will be left behind after the procedure is run.

The PERL_ROOT will be set to a compatible perl if such a perl is found and
is not the default PERL_ROOT:.  This setting will persist after the test.

This wrapper should be run with the default set to the base directory
of the make source.

The HELP parameter will bring up this text and then run the help script
for the Perl wrapper.  Not all options for the perl script have been
implemented, such as valgrind or specifying the make path or source path.

Running the wrapper script requires:
  Perl 5.18 or later.
  PCSI kits available from http://sourceforge.net/projects/vmsperlkit/files/

  GNV 2.1.3 or later.  GNV 3.0.1 has not tested with this script.
  Bash 4.2.47 or later.
  Coreutils 8.21 or later.
  http://sourceforge.net/projects/gnv/files/
  Read before installing:
     http://sourceforge.net/p/gnv/wiki/InstallingGNVPackages/
  As updates for other GNV components get posted, those updates should
  be used.
