+=head1 NAME
+
+Bugzilla - Semi-persistent collection of various objects used by scripts
+and modules
+
+=head1 SYNOPSIS
+
+  use Bugzilla;
+
+  Bugzilla->create;
+
+  sub someModulesSub {
+    my $B = Bugzilla->instance;
+    $B->template->process(...);
+  }
+
+=head1 DESCRIPTION
+
+Several Bugzilla 'things' are used by a variety of modules and scripts. This
+includes database handles, template objects, and so on.
+
+This module is a singleton intended as a central place to store these objects.
+This approach has several advantages:
+
+=over 4
+
+=item *
+
+They're not global variables, so we don't have issues with them staying arround
+with mod_perl
+
+=item *
+
+Everything is in one central place, so its easy to access, modify, and maintain
+
+=item *
+
+Code in modules can get access to these objects without having to have them
+all passed from the caller, and the caller's caller, and....
+
+=item *
+
+We can reuse objects across requests using mod_perl where appropriate (eg
+templates), whilst destroying those which are only valid for a single request
+(such as the current user)
+
+=back
+
+Note that items accessible via this object may be loaded when the Bugzilla
+object is created, or may be demand-loaded when requested.
+
+For something to be added to this object, it should either be able to benefit
+from persistence when run under mod_perl (such as the a C<template> object),
+or should be something which is globally required by a large ammount of code
+(such as the current C<user> object).
+
+=head1 CREATION
+
+=over 4
+
+=item C<create>
+
+Creates the C<Bugzilla> object, and initialises any per-request data
+
+=item C<instance>
+
+Returns the current C<Bugzilla> instance. If one doesn't exist, then it will
+be created, but no per-request data will be set. The only use this method has
+for creating the object is from a mod_perl init script. (Its also what
+L<Class::Singleton> does, and I'm trying to keep that interface for this)
+
+=back
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item C<template>
+
+The current C<Template> object, to be used for output
+
+=item C<cgi>
+
+The current C<cgi> object. Note that modules should B<not> be using this in
+general. Not all Bugzilla actions are cgi requests. Its useful as a convenience
+method for those scripts/templates which are only use via CGI, though.
