The mechanic takes advantage of eruby portablity and simplicity to create a blog application [1]. The script uses flat-files for a data source. This is a great beginners tutorial that shows how to create the dynamic menus and setup things cleanly on the server.
Mechanic leaves the setting up of eRuby over to others like Hiveminds Magazine. So if you are looking for something to experiment with right after you check out the eRuby for the web [2] tutorial then give the mechanic [3] a click.
Happy Publishing!
