This module implements a \s-1GNU\s0 grep-based mbox folder reader. It can only be used when \s-1GNU\s0 grep is installed on the system. Users must not instantiate this class directly\*(--use Mail::Mbox::MessageParser instead. The base MessageParser module will automatically manage the use of grep and non-grep implementations.
