deb_hand.mak

# Create .deb without using dpkg tools.
#
# Author: Tim Wegener <twegener@madabar.com>
#
# Use 'include deb_hand.mak' after defining the user variables in a local
# makefile.
#
# The 'data' rule must be customised in the local make file.
# This rule should make a 'data' directory containing the full file
# layout of the installed package.
#
# This makefile will create a debian-binary file a control directory and a
# a build directory in the current directory.
# Do 'make clobber' to remove these generated files.
#
# Destination:
# PACKAGE_DIR - directory where package (and support files) will be built
#               defaults to the current directory
#
# Sources:
# SOURCE_DIR - directory containing files to be packaged
# ICON_SOURCE - 26x26 icon file for maemo
# DESCR - description with summary on first line
# preinst, postinst, prerm, postrm - optional control shell scripts

# These fields are used to build the control file:
# PACKAGE = 
# VERSION = 
# ARCH = 
# SECTION = 
# PRIORITY = 
# MAINTAINER = 
# DEPENDS = 
#
# SOURCE_DIR =
# ICON_SOURCE = 
# (ICON_SOURCE is optional)

# *** NO USER CHANGES REQUIRED BEYOND THIS POINT ***
