-# Build a BackupPC distribution
+# makeDist: Build a BackupPC distribution
 #
+# DESCRIPTION
+#
+#   This script should be run with no arguments to build a
+#   distribution.  The $Version and $ReleaseDate should be
+#   edited below to specify the version name and the release
+#   date.  The distribution is createede in the sub-directory
+#   dist.  The dsitribution is in the file name:
+#
+#           dist/BackupPC-$Version.tar.gz.
+#
+#   Often the language files are not up to date, and makeDist
+#   exits after complaining about the lang files being inconsistent.
+#   Use the -nolangCheck option to turn off that behavior.
