Source code for scripts.misspelling

This script fixes links that contain common spelling mistakes.

This is only possible on wikis that have a template for these misspellings.

Command line options:

   -always:XY  instead of asking the user what to do, always perform the same
               action. For example, XY can be "r0", "u" or "2". Be careful with
               this option, and check the changes made by the bot. Note that
               some choices for XY don't make sense and will result in a loop,
               e.g. "l" or "m".

   -main       only check pages in the main namespace, not in the Talk,
               Project, User, etc. namespaces.

   -start:XY   goes through all misspellings in the category on your wiki
               that is defined (to the bot) as the category containing
               misspelling pages, starting at XY. If the -start argument is not
               given, it starts at the beginning.
