+Lifetype JSON Export
+
+Create a JSON representation of all of the blog posts inside a lifetype
+blog, for backups or import to another blog engine.
+
+A quick PHP script that, using the LifeType API, exports your post data in 
+a JSON format.
+
+This script can be placed in the LifeType root directory.
+
+Simply drop this script into your LifeType folder, and visit it in a web 
+browser or via curl/wget.
