NAME
    CPAN::Testers::Common::Utils - Utility functions for CPAN Testers
    modules

VERSION
    This documentation describes version 0.001.

SYNOPSIS
         use CPAN::Testers::Common::Utils ':all';
 
         # NNTP ID <=> GUID mapping
         $guid    = nntp_to_guid( $nntp_id );
         $nntp_id = guid_to_nntp( $guid    );

DESCRIPTION
    This module contains common utility functions for use by other CPAN
    Testers modules

USAGE
  Mapping NNTP IDs to GUIDS
    Legacy CPAN Testers reports were sent via email and made available via
    an NNTP group, perl.cpan.testers. Reports were 'indexed' by their NNTP
    ID. The next generation of CPAN Testers uses a GUID to identify reports.

    Old reports with an NNTP ID are mapped to GUIDs by replacing the first 8
    hex characters of a common 'base GUID' with a zero-padded decimal
    representation of the NNTP ID.

       XXXXXXXX-B19F-3F77-B713-D32BBA55D77F

    Such GUIDS are visually distinctive and have the nice feature of sorting
    earlier than second-generated report GUIDS based on a timestamp.

    Two translation functions are provided for convenience.

    `nntp_to_guid'
         $guid    = nntp_to_guid( $nntp_id );

    Given a numeric NNTP ID, returns a standard string-form GUID. (No range
    checking is done.) Examples:

       nntp_to_guid( 51432   );  # 00051432-B19F-3F77-B713-D32BBA55D77F
       nntp_to_guid( 6171265 );  # 06171265-B19F-3F77-B713-D32BBA55D77F

    `guid_to_nntp'
         $guid    = nntp_to_guid( $nntp_id );

    Given a GUID of the form described above, returns the decimal number in
    the first 8 characaters. (Again, there is no error checking that the
    GUID is properly formatted.) Examples:

       guid_to_nntp( '00051432-B19F-3F77-B713-D32BBA55D77F' ); # 51432
       guid_to_nntp( '06171265-B19F-3F77-B713-D32BBA55D77F' ); # 6171265
