+`Max M`_ had often needed to parse and generate iCalendar files. Finally, he got
 tired of writing ad-hoc tools. This package is his attempt at making an
 iCalendar package for Python. The inspiration has come from the email package
 in the standard lib, which he thinks is pretty simple, yet efficient and
 powerful.
 
-At the time of writing this, last version was released more then 2 years ago.
-Since then many things have changes. For one, `RFC 2445`_ was updated by `RFC
-5545`_ which makes this package. So in some sense this package became outdated.
+The icalendar package is an RFC 5545-compatible parser/generator for iCalendar files.
