INHERITANCE

        Mail::Box::MH::Labels
          is a Mail::Reporter

SYNOPSIS

        my $labels = Mail::Box::MH::Labels->new;
        $labels->read(...)
        $labels->write(...)

DESCRIPTION

       MH type message folders use one dedicated file per folder-directory to list special tags
       to messages in that folder.  By doing this, mail agents may avoid parsing all the
       messages, which is very resource consuming.

       Labels can be used to group messages, for instance to reflect which messages have been
       read or which look like spam.  Some labels are predefined, but more can be added without
       limitation.

       Extends "DESCRIPTION" in Mail::Reporter.

DIAGNOSTICS

       Error: Package $package does not implement $method.
           Fatal error: the specific package (or one of its superclasses) does not implement this
           method where it should. This message means that some other related classes do
           implement this method however the class at hand does not.  Probably you should
           investigate this and probably inform the author of the package.
