# Description   : JATS Make Time Support. Command File Generation
#                 This package contains useful functions for the generation of
#                 runtime command files. It extends the binary executable "cmdfile"
#                 but it is intended to:
#                       Be better documented
#                       Have better argument parsing
#                       Not require compilation
#
#                 The functions are designed to be invoked as:
#                   $(GBE_PERL) -Mjats_cmdfile -- <args>+
#
#  Notes        :   Keep this package simple
#                   Don't use all the JATS infrastructure.
