"""
|
|
This serves lexonomy plugins
|
|
This almost just returns static files,
|
|
it only does search-and-replace for
|
|
$LOCATION$ -> location of plugin
|
|
every plugin is its own folder and if folder is
|
|
"myplugin" and this website's url is "http://example.com",
|
|
then $LOCATION$ gets the value of http://example.com/myplugin
