r"""
Bot to upload pages from a text file.

This bot takes its input from the UTF-8 text file that contains
a number of pages to be put on the wiki. The pages should all have
the same beginning and ending text (which may not overlap).
The beginning and ending text is not uploaded with the page content
by default.

As a pagename is by default taken the first text block
from the page content marked in bold (wrapped between ''' and ''').
If you expect the page title not to be present in the text
or marked by different markers, use -titlestart, -titleend,
and -notitle parameters.

Specific arguments:

-file:xxx       The filename we are getting our material from,
                the default value is "dict.txt"
-begin:xxx      The text that marks the beginning of a page,
                the default value is "{{-start-}}"
-end:xxx        The text that marks the end of the page,
                the default value is "{{-stop-}}"
-include        Include the beginning and end markers to the page
-textonly       Text is given without markers. Only one page text is given.
                -begin and -end options are ignored.
-titlestart:xxx The text used in place of ''' for identifying
                the beginning of a page title
-titleend:xxx   The text used in place of ''' for identifying
                the end of the page title
-notitle        Do not include the page title, including titlestart
                and titleend, to the page. Can be used to specify unique
                page title above the page content
-title:xxx      The page title is given directly. Ignores -titlestart,
                -titleend and -notitle options
-nocontent:xxx  If the existing page contains specified statement,
                the page is skipped from editing
-noredirect     Do not upload on redirect pages
-summary:xxx    The text used as an edit summary for the upload.
                If the page exists, standard messages for prepending,
                appending, or replacement are appended after it
-autosummary    Use MediaWiki's autosummary when creating a new page,
                overrides -summary
-minor          Set the minor edit flag on page edits
-showdiff       Show difference between current page and page to upload,
                also forces the bot to ask for confirmation
                on every edit

If the page to be uploaded already exists, it is skipped by default.
But you can override this behavior if you want to:

-appendtop      Add the text to the top of the existing page
-appendbottom   Add the text to the bottom of the existing page
-force          Overwrite the existing page

It is possible to define a separator after the 'append' modes which
is added between the existing and the new text. For example
a parameter -appendtop:foo would add 'foo' between them. A new line
can be added between them by specifying '\n' as a value.
