# Module name   : jats.sh

# Module type   : Makefile system

# Compiler(s)   : n/a

# Environment(s): jats

#

# Description   : This package extends the JATS toolset at build time

#                 It provides additional directives to the JATS makefiles

#                 to simplify the directives.

#

#                 The directive matches up with a run-time tool to

#                 do the bulk of the work.

#

# Operation     : This package adds the JATS directive MakeDebianPackage

#                 When used the directive will use GenerateFiles to invoke

#                 a script (DebianPackager.pl) to actually do the hard work.

#

# Syntax        : MakeDebianPackage (<platforms>, Options+);

#                 Where Options may be one of:

#                   --Script=PackagerScript             - Mandatory. Name of a the packaging script

#                   --Name=Name                         - Debian Package name(optional)

#                   --Variant=Text                      - Package Variant(optional)

#                   --VersionPrefix=Text                - Prefixes the version with the passed text(optional)

#                   --ExtDesc=Text                      - Stored in the variable $opt_extdesc availabe in the

#                                                         packaging script(optional)

#                   --DeployMode                        - Create Deployable packages(optional)

#                                                         Default for native targets

#                                                         These are:

#                                                           * Packaged into the root of target pkg

#                                                           * Have P or D in the name

#                   --NoDeployMode                      - Create packages that cannot be directly deployed

#                                                         Default for embedded devices

#                   --TarFile[=TemplateName]            - Create named .tgz file, of the data area [not Debian scripts]

#                   --TarFile                           - Same as --TarFile=PACKAGE_VERSION_PLATFORM_TYPE or PACKAGE_VERSION_PLATFORM

#                   --TarOnly                           - Suppress the Debian Build

#                   --NoArch                            - Marks the package as having no specific architecture

#                   

#

#               Templates may contain:
