"""
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:

-always           The bot won't ask for confirmation when putting a page

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

-replace:         Don't add text but replace it

-top              Place additional text on top of the page

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

This sample script is a
:py:obj:`ConfigParserBot <bot.ConfigParserBot>`. All settings can be
made either by giving option with the command line or with a settings file
which is scripts.ini by default. If you don't want the default values you can
add any option you want to change to that settings file below the [basic]
section like:

    [basic] ; inline comments starts with colon
    # This is a commend line. Assignments may be done with '=' or ':'
    text: A text with line break and
        continuing on next line to be put
    replace: yes ; yes/no, on/off, true/false and 1/0 is also valid
    summary = Bot: My first test edit with pywikibot

Every script has its own section with the script name as header.

In addition the following generators and filters are supported but
cannot be set by settings file:
