+# NAME
+# reformat-html - reformat HTML files from emailselfdefense.fsf.org
+
+# SYNOPSIS
+# reformat-html /PATH/TO/NAME.html
+
+# GRAPHIC INTERFACE HOWTO
+# * Launch the script by double-clicking on it; a terminal will open.
+# * At the prompt, drag and drop the input file into the terminal.
+#
+# Alternatively (in Gnome, KDE, XFCE, etc.)
+# * create a launcher for the application menu;
+# * launch the script from the contextual menu of the HTML file.
+#
+# The reformatted file is created in the directory where the input file
+# resides, and its name is NAME-r.html.
