 **Description**: Import blog posts from Wordpress using their export tool. Blog entries will be read from the XML and converted into .post files. Afterwards the XML file will be deleted to prevent reimporting. Optionally an ```:output``` argument may be supplied to the plugin. If provided, it should be a directory in which to store the .post files. Otherwise, the value of ```:repo``` in your .coleslawrc will be used.
 
 **Example**: ```(import :filepath "/home/redline/redlinernotes-export.timestamp.xml" :output "/home/redlinernotes/blog/")```
