+# Usage: rss-title-filter <list of titles to include>
+#
+#        Skips all items which do NOT include the given titles.
+#
+#        Example: to include all entries with the title "meme", "quiz" or
+#        "picture post", do:
+#
+#        rss-title-filter meme quiz "picture post"
+#
+#        Requires the Ruby RSS module, which is included in Ruby 1.8.3 or
+#        higher and available for older versions of Ruby at
+#        http://raa.ruby-lang.org/project/rss/.
+#
+#        based on "rss-tag-filter" by Joe Mason.
