-Identi.ca Tools

-
-This plugin is heavily based on Alex King's original Twitter Tools plugin,
-available at http://alexking.org/projects/wordpress. As the Identi.ca
-(http://identi.ca) microblogging service has a 100% Twitter-compatible API, it
-was trivial to adapt his plugin. If you find this useful, please visit Alex
-King's website and donate. He's the one who did all the real programming work;
-most of the work I did was simple string searching-and-replacing.
-
-Many thanks also to Evan Prodromou and the rest of the good folks at
-Laconi.ca (http://laconi.ca) and Identi.ca (http://identi.ca). Their hard
-work on implementing the Twitter-compatible API greatly simplified this
-port.
