If the first lines of code have the comment #title=New Title, the page title is renamed to New Title. If the comment is #autorun, the code is automatically run.
This reads the first 3 lines of your code, and does the following:
#title=New Code Titlethen the page's title is changed to New Code Title (or whatever name you specify in the comment)
#autorunthe code is automatically run when the page is loaded.
