DESCRIPTION

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