Get the current load status, which can be any of the following: 0 nothing loaded yet 'SHARE' sharedir loaded 'BOTH' sharedir _and_ sitedir loaded
sharedir
Get the sharedir attribute, i.e. the full path of the site configuration directory (available only after sharedir has been successfully loaded)

Get the sitedir attribute, i.e. the full path of the site configuration directory (available only after sitedir has been successfully loaded)
supported_languages
Get $supported_languages array ref from App::CELL::Message
load
Attempt to load messages and configuration parameters from the sharedir and, possibly, the sitedir as well.
Takes: a PARAMHASH that should include appname and at least one of enviro or sitedir (if both are given, enviro takes precedence with sitedir as a fallback).
Returns: an App::CELL::Status object, which could be any of the following: OK success WARN previous call already succeeded, nothing to do ERR failure
On success, it also sets the CELL_META_START_DATETIME meta parameter.
set_meta
Set a meta parameter. Wrapper for App::CELL::Config::set_meta. Takes two arguments: string containing name of meta parameter, and value (scalar, arrayref, or hashref) to assign to the parameter. Returns a status object.
msg
Construct a message object (wrapper for App::CELL::Message::new)
