Well, I told you it was beta software! :-)

* The module "caches" the unparsed text files, really for no reason at
  all. This means that the module may take up quite some memory as the
  total text size grows. Reloading the module flushes the cache.

* The --8<-- text excerpt --8<-- feature can only be used once per
  file, which is a really ugly limitation.

* There must be at least one diary entry present before the module
  will work.

* The module is not year 2036 safe yet. :-)
