The Writegood scripts can be handy if you write non-fiction prose in Vim.

A strange synchronicity: I came across the page at

http://matt.might.net/articles/shell-scripts-for-passive-voi...

and duly copy/pasted the bash scripts and ran them over some text files. Quite useful. Then I saw this thread and wondered if anyone had done a vim plug in for them. And davidbeckingsale has.
