Poem Example

In Xanadu did Kubla Khan
  A stately pleasure-dome decree:
Where Alph, the sacred river, ran
  Through caverns measureless to man
  Down to a sunless sea.

So twice five miles of fertile ground
With walls and towers were girdled round:
  And there were gardens bright with sinuous rills,
  Where blossomed many an incense-bearing tree;
And here were forests ancient as the hills as well as an extremely long non-canonical line in the poem that was mostly used by Wei-Hwa to demonstrate the word-wrapping features of this extension to Mediawiki even though it doesn't work with this poem at all for any lyrical purpose,
Enfolding sunny spots of greenery.
