"""
An incomplete sample script.

This is not a complete bot; rather, it is a template from which simple
bots can be made. You can rename it to mybot.py, then edit it in
whatever way you want.

Use global -simulate option for test purposes. No changes to live wiki
will be done.

The following parameters are supported:

&params;

-always           If used, the bot won't ask if it should file the message
                  onto user talk page.

-text:            Use this text to be added; otherwise 'Test' is used

-replace:         Dont add text but replace it

-top              Place additional text on top of the page

-test:            Switch on test prinouts

-summary:         Set the action summary message for the edit.
