$(basename $0) is used to convert 32-bit Slackware packages
to compatibility packages for 64-bit variants.
required parameters::
-i input_package_file_name : 32-bit package to convert
optional parameters::
-d destination_directory : create package in this directory
-o output_package_file_name : package name to create
-s output_slack_desc : slack-desc to use for new package
environment variables:
ARCH (target architecture; defaults to \$(uname -m))
BUILD (build number for output package; defaults to same as input package.
output_package_file_name overrides this value)
OUTPUT (location to create the package; defaults to /tmp)
