r"""
Append text to the top or bottom of a page.
By default this adds the text to the bottom above the categories and interwiki.
Use the following command line parameters to specify what to add:
-text Text to append. "\n" are interpreted as newlines.
-textfile Path to a file with text to append
-summary Change summary to use
-up Append text to the top of the page rather than the bottom
-create Create the page if necessary. Note that talk pages are
created already without of this option.
-createonly Only create the page but do not edit existing ones
-always If used, the bot won't ask if it should add the specified
text
-major If used, the edit will be saved without the "minor edit" flag
-talkpage Put the text onto the talk page instead
-talk
-excepturl Skip pages with a url that matches this regular expression
-noreorder Place the text beneath the categories and interwiki
Furthermore, the following can be used to specify which pages to process...
¶ms;
Examples
--------
1. Append 'hello world' to the bottom of the sandbox:
python pwb.py add_text -page:Wikipedia:Sandbox \
-summary:"Bot: pywikibot practice" -text:"hello world"
2. Add a template to the top of the pages with 'category:catname':
python pwb.py add_text -cat:catname -summary:"Bot: Adding a template" \
-text:"{{Something}}" -except:"\{\{([Tt]emplate:|)[Ss]omething" -up
3. Command used on it.wikipedia to put the template in the page without any
category:
python pwb.py add_text -except:"\{\{([Tt]emplate:|)[Cc]ategorizzare" \
-text:"{{Categorizzare}}" -excepturl:"class='catlinks'>" -uncat \
-summary:"Bot: Aggiungo template Categorizzare"
