package GO::AppHandles::AppHandleCWrapper;

=head1 NAME

GO::AppHandles::AppHandleCWrapper

=head1 SYNOPSIS

you should never use this class directly. Use GO::AppHandle
(All the public methods calls are documented there)

=head1 DESCRIPTION

implementation of GO::AppHandle that uses an underlying C library for
speed
