 # This file goes through all the necessary steps to build a release package.
-# You may specify a OS major version number (4, 5, or 6) to specify which
-# OS release to build. If no version number is given it will default to 6.
+# syntax:
+#     mkrelease.sh [5] [clean] [targets ....]
+#
+# You may specify 5 to build for IRIX 5.3
+#
+# You can specify clean to do a make clean before building. Make clean
+# will also run configure and generate the required Makefile.
+#
+# You can specify which targets to build. If targets are specified, the
+# specified targets will be built but inst packages will not be generated.
