This plugin counts words in a page. For a single page, write a [[!wordcount ]] directive and the word count will be interpolated there. For a site, add <TMPL_VAR WORDCOUNT> to your templates.

If HTML::Strip is installed, the wordcount will be slightly more accurate.

Possible enhancements:

• Optimize: count words iff the result will be displayed. sanitize() seems like the right place to count. Since it's called well after preprocess(), I can tell whether a directive needs the result, but since it appears to be called before pagetemplate(), I can't tell whether a template wants to know and possibly skip the computation. (In other words, if I add $needed_for_template like $needed_for_directive, it gets set too late for sanitize() to see.)
