  } );


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

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 are encouraged to use Mail::Mbox::MessageParser instead. The base MessageParser module will automatically fall back to another reader implementation if this module can not be used.

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. file_name is the filename of the mailbox. The file_handle argument is the opened file handle to the mailbox. Both arguments are required.
