+# This script generates a tarball of source code and screenshots,
 # 'htdocs_plot_examples.tgz', that will be part of the 'examples' web page,
 #
+# The original intention was to upload the generated tarball directly to the 
+# PLplot SourceForge website filesystem and unpack it there using ssh
+# commands, but now that SF is no longer ssh accessible, the script
+# has been generalized for any ssh-accessible site, which in turn can
+# be used to update the SF website using rsync.
+
 # This script must be run in the top plplot source directory as:
 #
-#     scripts/htdocs-gen_plot-examples.sh
+# WWW_USER=$USERNAME \
+# WWW_GROUP=$GROUPNAME \
+# WWW_HOST=$HOSTNAME \
+# WWW_DIR=$WEBSITE_PREFIX \
+# scripts/htdocs-gen_plot-examples.sh
 #
-# The tarball will be copied to SourceForge and unpacked at the www area.
-# If your user name (as given by the environment variable USER) is different
-# as that at SF, then launch the script like this:
-#
-#     WWW_USER=joeplplotter scripts/htdocs-gen_plot-examples.sh
-#
-# It is also possible to override the variables WWW_GROUP, WWW_HOST,
-# and WWW_DIR in the same way as with WWW_USER in the example above.
-#
+# where $USERNAME, $GROUPNAME, $HOSTNAME, and $WEBSITE_PREFIX are the
+# appropriate username, groupname, hostname, and website prefix directory
+# of the ssh-accessible site.

 # To avoid rebuild launch it like this:
-#     build=false scripts/htdocs-gen_plot-examples.sh

+# WWW_GROUP=$GROUPNAME \
+# WWW_HOST=$HOSTNAME \
+# WWW_DIR=$WEBSITE_PREFIX \
