Apache::Wyrd::Bot - Spawn a process and monitor it

=head1 SYNOPSIS

  <BASENAME::Bot basefile="/var/www/watchme" perl="/usr/bin/perl" />

=head1 DESCRIPTION

The Bot Wyrd provides a class of objects which operate in
the background and independent of the apache process, while
being monitored in a browser window.  This is useful for
showing updates to a time-consuming process, such as
building an index or converting a file between different
formats.

Because it uses HTML http-equivalent metadata to trigger the
browser reload, it should always be the outermost Wyrd on an
HTML page.

Bot uses the default UNIX shell and the machine filesystem

word-searching for dynamic content on a page is solved by refreshing the
meta-information cache of a page when the dynamic content on it changes. 
Often, Widget objects are used to contain Pulls in this way so that
word-search data on a page is kept accurate.

=head2 IndexBots

The question of how to efficiently create onetime "builds" of the Index
cache is answered by the [MySQL]IndexBot class.  This is a combination Wyrd
and Bot (See Apache::Wyrd::Bot), which when served up causes an
Apache::Wyrd::Bot process to be launched in the background, systematically
requesting every page in the site to be served up, causing the index on each
page to be refreshed.  The bredth of these requests can be limited by file
modification date since a cached date to reduce the time for this build to
take.

=head2 Other Objects in the Apache::Wyrd::Site Hierarchy

This hierarchy is meant to be somewhat more volitile than the rest of the
Apache::Wyrd classes.  As useful objects following these conventions come
into common usage, they will be added to the area, but may not be adequately
