.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
It is often useful for a single master configuration to be shared across
multiple modules in an application.  Config::Onion::Simple provides an
interface to do this without requiring any of those modules to know about
each other.
.SH "EXPORTABLE FUNCTIONS"
.IX Header "EXPORTABLE FUNCTIONS"
Config::Onion::Simple exports nothing by default.  The following functions
are exported only on request.
.SS "cfg"
.IX Subsection "cfg"
Returns a reference to the complete configuration hash managed by the
Config::Onion singleton.  This hash should be treated as read-only, as any
changes will be lost if the configuration is altered using the underlying
Config::Onion instance's methods.
.PP
Calling \f(CW\*(C`cfg\*(C'\fR is equivalent to calling \f(CW\*(C`cfg_obj\->get\*(C'\fR.
.SS "cfg_obj"
.IX Subsection "cfg_obj"
Returns a reference to the Config::Onion singleton.  Use this object's methods
to make any changes to the configuration.
