+# Script to convert all files (tarballs in any format; just recognized
+# by 'tar') within an 'odir' to a unified '.tar.lz' format.
+#
+# The inputs are assumed to be formatted with 'NAME_VERSION', and only for
+# the names, we are currently assuming '.tar.*' (for the 'sed'
+# command). Please modify/generalize accordingly.
+#
+# It will unpack the source in a certain empty directory with the
+# 'tmpunpack' suffix, and rename the top directory to the requested format
+# of NAME-VERSION also. So irrespective of the name of the top original
+# tarball directory, the resulting tarball's top directory will have a name
+# formatting of NAME-VERSION.
