# Description   : JATS Make Time Test Harness Support
#                 This package contains fucntions that will be used by JATS
#                 to invoke the tests.
#
#                 This is more powerful that the previous shell-based solution
#                 that had problems under windows.
#
#                 The functions are designed to be invoked as:
#                   $(GBE_PERL) -Mjats_runtest -e <function> -- <args>+
#
#                 The functions in this packages are designed to take parameters
#                 from @ARVG as this makes the interface easier to read.
