I'm posting this using a bare-boned atom-blogger that I implemented this morning.
It uses curl to process the HTTP Post Request.
Editting Previous Entries
What's more, the bare-bones atom-blogger can now edit previous posts.
This is done by getting the desired entry, filtering it for elements that should not be present when submitting updates, and adding a generator element --- all of these steps are required by the Blogger API.
Unwanted elements are filtered out using xsltproc.
