"""
This is a Bot written by Filnik to add a text at the end of the page but above
categories, interwiki and template for the stars of the interwiki (default).

Alternatively it may also add a text at the top of the page.
These command line parameters can be used to specify which pages to work on:

&params;

Furthermore, the following command line parameters are supported:

-page             Use a page as generator

-talkpage         Put the text onto the talk page instead the generated on
-talk

-text             Define which text to add. "\n" are interpreted as newlines.

-textfile         Define a texfile name which contains the text to add

-summary          Define the summary to use

-except           Use a regex to check if the text is already in the page

-excepturl        Use the html page as text where you want to see if there's
                  the text, not the wiki-page.

-newimages        Add text in the new images

-untagged         Add text in the images that don't have any license template

-always           If used, the bot won't ask if it should add the text
                  specified

-up               If used, put the text at the top of the page

--- Example ---
1.
# This is a script to add a template to the top of the pages with
# category:catname
# Warning! Put it in one line, otherwise it won't work correctly.

python add_text.py -cat:catname -summary:"Bot: Adding a template"
-text:"{{Something}}" -except:"\{\{([Tt]emplate:|)[Ss]omething" -up

2.
# Command used on it.wikipedia to put the template in the page without any
# category.
# Warning! Put it in one line, otherwise it won't work correctly.

python add_text.py -excepturl:"class='catlinks'>" -uncat
-text:"{{Categorizzare}}" -except:"\{\{([Tt]emplate:|)[Cc]ategorizzare"
-summary:"Bot: Aggiungo template Categorizzare"
