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.
