NAME
       Mail::Mbox::MessageParser::MetaInfo - A cache for folder metadata

DESCRIPTION
       This module implements a cache for meta-information for mbox folders. The information includes such items such as the
       file position, the line number, and the byte offset of the start of each email.

   METHODS AND FUNCTIONS
       SETUP_CACHE(...)
             SETUP_CACHE( { 'file_name' => <cache file name> } );

             <cache file name> - the file name of the cache

           Call this function once to set up the cache before creating any parsers. You must provide the location to the cache
           file. There is no default value.

           Returns an error string or 1 if there is no error.

       CLEAR_CACHE();
           Use this function to clear the cache and delete the cache file.  Normally you should not need to clear the cache--the
           module will automatically update the cache when the mailbox changes. Call this function after SETUP_CACHE.

       WRITE_CACHE();
           Use this function to force the module to write the in-memory cache information to the cache file. Normally you do not
           need to do this--the module will automatically write the information when the program exits.

       $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. This will be used as
           the cache key, so it's important that it fully defines the path to the mailbox. The file_handle argument is the
           opened file handle to the mailbox. Both arguments are required.

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