# autoipkg.sh ( Version 0.3 )
#
# A quick hack to automatically build ipkgs from autoconf based source 
# packages.
#
# Usage is like:
# 
#    DEPS=xlibs DESC="foo" MAINTAINER='foo@foo.com' autoipkg --enable-foo
#
# Or Alternatively a .autopkg in the working dir will be checked for and 
# params set there used. 
#
# The following Params are understood;
#
#  PACKAGE              Package name ( auto detected )
#  VERSION              Package version ( auto detected )
#  ARCH                 Package arch ( defualts to arm )
#  REV			Package Revision
#  MINOR_VERSION        Extra Version info - eg '.12345'
#  MAINTAINER           Maintainer, defaults to user@hostname
#  SOURCE		Source URL
#  DEPS			List of package deps
#  DESC			Package description
#  CONFIGURE_ARGS	Args to pass to configure ( prefix is set to /usr )
#  EXTRA_CONTROL	Any extra lines to add to control
#  INTERACTIVE		Set to 'n' for non-interactive build 
#    POSTINST		Postinst file location ( only for non-interactive )
#    POSTRM		postrm file location   ( only for non-interactive )
