User-interface related functions for building bots.

This module supports several different bot classes which could be used in
conjunction. Each bot should subclass at least one of these four classes:

* L{BaseBot}: Basic bot class in case where the site is handled differently,
  like working on two sites in parallel.

* L{SingleSiteBot}: Bot class which should only be run on a single site. They
  usually store site specific content and thus can't be easily run when the
  generator returns a page on another site. It has a property C{site} which
  can also be changed. If the generator returns a page of a different site
  it'll skip that page.

* L{MultipleSitesBot}: Bot class which supports to be run on multiple sites
  without the need to manually initialize it every time. It is not possible to
  set the C{site} property and it's deprecated to request it. Instead site of
  the current page should be used. And out of C{run} that sit isn't defined.

* L{ConfigParserBot}: Bot class which supports reading options from a
  scripts.ini configuration file. That file consists of sections, led by a
  C{[section]} header and followed by C{option: value} or C{option=value}
  entries. The section is the script name without .py suffix. All options
  identified must be predefined in available_options dictionary.

* L{Bot}: The previous base class which should be avoided. This class is mainly
  used for bots which work with wikibase or together with an image repository.

Additionally there is the L{CurrentPageBot} class which automatically sets the
current page to the page treated. It is recommended to use this class and to
use C{treat_page} instead of C{treat} and C{put_current} instead of C{userPut}.
It by default subclasses the C{BaseBot} class.

With L{CurrentPageBot} it's possible to subclass one of the following classes
to filter the pages which are ultimately handled by C{treat_page}:

* L{ExistingPageBot}: Only handle pages which do exist.
* L{CreatingPageBot}: Only handle pages which do not exist.
* L{RedirectPageBot}: Only handle pages which are redirect pages.
* L{NoRedirectPageBot}: Only handle pages which are not redirect pages.
* L{FollowRedirectPageBot}: If the generator returns a redirect page it'll
  follow the redirect and instead work on the redirected class.

It is possible to combine filters by subclassing multiple of them. They are
new-style classes so when a class is first subclassing L{ExistingPageBot} and
then L{FollowRedirectPageBot} it will also work on pages which do not exist
when a redirect pointed to that. If the order is inversed it'll first follow
them and then check whether they exist.

Additionally there is the L{AutomaticTWSummaryBot} which subclasses
L{CurrentPageBot} and automatically defines the summary when C{put_current} is

(Global arguments available for all bots)

-dir:PATH         Read the bot's configuration data from directory given by
                  PATH, instead of from the default directory.

-lang:xx          Set the language of the wiki you want to work on, overriding
                  the configuration in xx should be the
                  site code.

-family:xyz       Set the family of the wiki you want to work on, e.g.
                  wikipedia, wiktionary, wikivoyage, ...
                  This will override the configuration in

-site:xyz:xx      Set the wiki site you want to work on, e.g.
                  wikipedia:test, wiktionary:de, wikivoyage:en, ...
                  This will override the configuration in

-user:xyz         Log in as user 'xyz' instead of the default username.

-daemonize:xyz    Immediately return control to the terminal and redirect
                  stdout and stderr to file xyz.
                  (only use for bots that require no input from stdin).

-help             Show this help text.

-log              Enable the log file, using the default filename
                  Logs will be stored in the logs subdirectory.

-log:xyz          Enable the log file, using 'xyz' as the filename.

-nolog            Disable the log file (if it is enabled by default).

-maxlag           Sets a new maxlag parameter to a number of seconds. Defer bot
                  edits during periods of database server lag. Default is set

-putthrottle:n    Set the minimum time (in seconds) the bot will wait between
-pt:n             saving pages.

-debug:item       Enable the log file and include extensive debugging data
-debug            for component "item" (for all components if the second form
                  is used).

-verbose          Have the bot provide additional console output that may be
-v                useful in debugging.

-cosmeticchanges  Toggles the cosmetic_changes setting made in or
-cc      to its inverse and overrules it. All other
                  settings and restrictions are untouched.

-simulate         Disables writing to the server. Useful for testing and
                  debugging of new code (if given, doesn't do any real
                  changes, but only shows what would have been changed).
                  An integer or float value may be given to simulate a
                  processing time; the bot just waits for given seconds.

-<config var>:n   You may use all given numeric config variables as option and
                  modify it with command line.


For global options use -help:global or run -help
