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 availableOptions 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
used.

GLOBAL OPTIONS
==============
(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 user-config.py. xx should be the
language code.
-family:xyz Set the family of the wiki you want to work on, e.g.
wikipedia, wiktionary, wikitravel, ...
This will override the configuration in user-config.py.
-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
'%s-bot.log'
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
by config.py
-putthrottle:n Set the minimum time (in seconds) the bot will wait between
-pt:n saving pages.
-put_throttle:n
-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 config.py or
-cc user-config.py 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).
-<config var>:n You may use all given numeric config variables as option and
modify it with command line.
