 Usage

-curl rss_url | ./rssdl maildir
-./rssdl maildir <feed.rss
+curl rss_url | rssdl maildir
+rssdl maildir <feed.rss
 
 For atom feeds, pipe the feed through atom_content.sed and then through rssdl.
 
-curl atom_url | sed -f atom_content.sed | ./rssdl maildir
-sed -f atom_content.sed feed.atom | ./rssdl maildir
+curl atom_url | sed -f atom_content.sed rssdl maildir
+sed -f atom_content.sed feed.atom | rssdl maildir
+
+For certain feeds that use Dublin Core for specifying the published date, you
+can use sed to change the timezone portion of the date to workaround strftime(3)
+not recognizing colons in timezone offsets (%z).
+
+curl rss_url | sed '/dc:date/s,:,,4' | rssdl maildir
+sed '/dc:date/s,:,,4' feed.rss | rssdl maildir
