# Module name   : DebianPackager.pl

# Module type   : Makefile system

# Compiler(s)   : Perl

# Environment(s): jats

#

# Description   : This program is invoked by the MakeDebianPackage and MakeRpmPackage

#                 directive that is a part of this package

#

#                 The program will use a user-provided script in order

#                 to create the output Package.

#

#                 The user script may call a number of directives in order to

#                 construct an image of the package being installed.

#

#                 The script specifies Debian/RPM configuration scripts that

#                 will be embedded in the package.

#

#                 This program will:

#                   Construct a filesystem image under control of the directives

#                   within the user script

#

#                   Debian:

#                       Massage the Debian control file

#                       Create a Debian Package

#                       Transfer it to the users 'BIN' directory, where it is available to be packaged.

#                       

#                   RedHat Package:    

#                       Generate rpmBuilder control files

#                       Create the RPM image

#                       Transfer it to the users 'BIN' directory, where it is available to be packaged.

#                   

#                   TarFile:

#                       Tar Gzip the image

#                       Transfer it to the users 'BIN' directory, where it is available to be packaged.

#

#                 Summary of directives available to the user-script:

#                       Message                 - Display progress text
