+# bin/html.sed - translate certain characters to HTML & entities

+#
+# This script will take certain characters, for instance '<', and convert them
+# to their respective html entity, for instance '&lt;', so that html lints do
+# not complain.
+#
+# usage:
+#
+#	cmd | sed -f bin/html.sed
+#
+#	sed -f bin/html.sed file > output
+#
+#	sed -i -f bin/html.sed file
+#
+# VERSION="1.0 2024-11-04"
+
+# IMPORTANT NOTE: the '&amp;' substitution MUST come first! This is because the
+# other substitutions have '&'s in them and if the '&amp;' came after it would
+# corrupt the '&'s in the string.
