No, it is not, and in my opinion it would also not be
desirable to do
so. Among the forbids in the robots.txt is the forbid to get edit
pages; without that it would be impossible to run the bot.
And I have now found robotparser, which will handle non-Wiki needs, but it
doesn't recognize situations for exceptions such as this. For bot edit
situations the restrictions are not needed because a username/password (or
site configuration) allows an implied override of bot restrictions.
I had more concern about standardize_notes.py fetching citation
descriptions from other sites, but I'll add robotparser to it.
