NAME

       App::CELL::Config -- load, store, and dispense meta parameters, core parameters, and site
       parameters

SYNOPSIS

           use App::CELL::Config qw( $meta $core $site );

           # get a parameter value (returns value or undef)
           my $value;
           $value = $meta->MY_PARAM;
           $value = $core->MY_PARAM;
           $value = $site->MY_PARAM;

           # set a meta parameter
           $meta->set( 'MY_PARAM', 42 );

           # set an as-yet undefined core/site parameter
           $core->set( 'MY_PARAM', 42 );
           $site->set( 'MY_PARAM', 42 );

DESCRIPTION

       The purpose of the App::CELL::Config module is to maintain and provide access to three
       package variables, $meta, $core, and $site, which are actually singleton objects,
       containing configuration parameters loaded by App::CELL::Load from files in the distro
       sharedir and the site configuration directory, if any.

       For details, read App::CELL::Guilde.

EXPORTS

       This module exports three scalars: the 'singleton' objects $meta, $core, and $site.

SUBROUTINES

   AUTOLOAD
       The "AUTOLOAD" routine handles calls that look like this:
          $meta->MY_PARAM
          $core->MY_PARAM
          $site->MY_PARAM

   DESTROY
       For some reason, Perl 5.012 seems to want a DESTROY method

   exists
       Determine parameter existence.

   get
       Wrapper for get_param

   get_param
       Get value of config param provided in the argument.

   get_param_metadata
       Routine to provide access not only to the value, but also to the metadata (file and line
       number where parameter was defined) associated with a given parameter.

       Takes: parameter name.  Returns: reference to the hash associated with the given
       parameter, or undef if no parameter found.

   set
       Use this function to set new params (meta/core/site) or change existing ones (meta only).
       Takes two arguments: parameter name and new value.  Returns a status object.
