Blosxom is unique in that it reads and writes weblog posts as files on your computer’s hard drive.
Click the Choose Blosxom Folder… button and identify the folder that contains your Blosxom weblog.
Running a script is optional. It’s called when an item is posted to your disk, and can be useful for post-processing the contents or synchronizing the weblog contents with a web server.
A %@ in the script command-line will be replaced with the path to the file just posted.
