+# Script to optionally download, modify and build the 'alink' v1.6 linker

+# usage:
+# $build_alink build_directory package_directory url
+#
+# build_directory:
+# A directory to extract the package files to and build. The directory will
+# be created if it does not already exist. (Note: files are not in a
+# directory when unzipped)
+#
+# package_directory:
+# The location of the package.  This location if it does exist will be
+# created and a package downloaded from the Internet if the 3rd parameter
+# url is specified.
+#
+# url:
+# Specify an optional url download location.  If not specified then the
+# package file already in the package_directory will be used.  If specified
+# then downloading only occurs if the required package is not already in
+# package_directory.
