NAME

       Mail::Mbox::MessageParser::Grep - A GNU grep-based mbox folder reader

SYNOPSIS

         #!/usr/bin/perl

         use Mail::Mbox::MessageParser;

         my $filename = 'mail/saved-mail';
         my $filehandle = new FileHandle($filename);

         my $folder_reader =
           new Mail::Mbox::MessageParser( {
             'file_name' => $filename,
             'file_handle' => $filehandle,
             'enable_grep' => 1,
           } );

         die $folder_reader unless ref $folder_reader;

         # Any newlines or such before the start of the first email
         my $prologue = $folder_reader->prologue;
         print $prologue;

         # This is the main loop. It's executed once for each email
         while(!$folder_reader->end_of_file());
         {
           my $email = $folder_reader->read_next_email();
           print $email;
         }

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 directly--use
       Mail::Mbox::MessageParser instead. The base MessageParser module will automatically manage
       the use of grep and non-grep implementations.

   METHODS AND FUNCTIONS
       The following methods and functions are specific to the Mail::Mbox::MessageParser::Grep
       package. For additional inherited ones, see the Mail::Mbox::MessageParser documentation.

       $ref = new( { 'file_name' => <mailbox file name>, 'file_handle' => <mailbox file handle>
       });
               <file_name> - The full filename of the mailbox
               <file_handle> - An opened file handle for the mailbox

           The constructor for the class takes two parameters. The file_name parameter is the
           filename of the mailbox. The file_handle argument is the opened file handle to the
           mailbox.

           Returns a reference to a Mail::Mbox::MessageParser object, or a string describing the
           error.

       end_of_file()
       reset()
       read_next_email()
           These methods are overridden in this subclass of Mail::Mbox::MessageParser.
