+# Copy external IRAF package source from the current working directory to
+# $PREFIX/iraf_extern/package_name, add any configuration files from the conda
+# recipe (eg. ur_extern.pkg), update extern.pkg accordingly, compile the
+# package and its help in place and remove any proprietary files. The build is
+# done using the installed copy since the package and its dependencies must
+# already be defined in IRAF at build time and IRAF packages are installed as a
+# source tree anyway.
+#
+# This script is used by the AstroConda build process (with no arguments and
+# the usual conda build variables set). Users wanting pre-built AstroConda IRAF
+# packages should install them with "conda install" or "conda create" instead.

+# Determine the directory this script lives in (for later use) and source some
+# common name definitions from the same place:
