# Module name   : DebianPackager.pl

# Module type   : Makefile system

# Compiler(s)   : Perl

# Environment(s): jats

#

# Description   : This program is invoked by the MakeDebianPackage

#                 directive, that is a part of this package

#

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

#                 to create a Debian 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 configuration scaripts that

#                 will be embedded in the package.

#

#                 This program will:

#                   Construct a filesystem image under control of the directives

#                   within the user script

#

#                   Massage the Debian control file

#

#                   Create a Debian Package

#

#                   Transfer it to the users 'BIN' directory, where it is

#                   available to be packaged.

#

#                 Summary of directives available to the user-script:

#                       AddInitScript           - Add an init script

#                       CatFile                 - Append to a file

#                       CopyDir                 - Copy directory tree

#                       CopyFile                - Copy a file

#                       CopyBinFile             - Copy an executable file

#                       CopyLibFile             - Copy a library file

#                       CreateDir               - Create a directory

#                       DebianFiles             - Specify control and script files

#                       DebianControlFile       - Specify control and script files

#                       DebianDepends           - Add Depends entry to control file

#                       EchoFile                - Place text into a file

#                       MakeSymLink             - Create a symbolic link

#                       PackageDescription      - Specify the package description

#                       SetFilePerms            - Set file permissions

#                       SetVerbose              - Control progress display

#                       IsProduct               - Flow control

#                       IsPlatform              - Flow control

#                       IsTarget                - Flow control

#                       IsVariant               - Flow control

#

#                 Thoughts for expansion:

#                       ConvertFile             - Option to convert file(s) to Unix Text

#                       ReplaceTags             - Replace Tags on target file

#                       SrcDir                  - Extend path for resolving local files

#

#                   Less used:

#                        ExpandLinkFiles        - Expand .LINK files

#

#                   Internal Use:

#                        FindFiles              - Find a file

#                        ResolveFile            - Resolve a 'local' source file

#

#

#                   The tool will attempt to copy a well-formed 'realname' library

#                   The soname of the library should be constructed on the target

#                   platform using ldconfig.

#                   There is no provision to copy the 'linker' name

#

#                   Given a request to copy a library called 'fred', then the

#                   well formed 'realname' will be:

#                           libfred[P|D|]].so.nnnnn

#                           [P|D|] indicates Production, Debug or None

#

#                   The 'soname' is held within the realname form of the library

#                   and will be created by lsconfig.

#

#                   The 'linkername' would be libfred[P|D|].so. This is only

#                   needed when linking against the library.

#

#

#                   The routine will also recognize Windows DLLs
