NAME

CPAN::Mini::LatestDistVersion - Create a CPAN mirror with only the latest version of each distribution

SYNOPSIS

    use CPAN::Mini::LatestDistVersion;
    
    CPAN::Mini::LatestDistVersion->update_mirror(
      remote => "http://cpan.metacpan.org/",
      local  => "/usr/share/mirrors/cpan",
    );
    
    # or via minicpan
    
    minicpan -c CPAN::Mini::LatestDistVersion

DESCRIPTION

CPAN::Mini uses the package index file (02packages.details.txt.gz) to grab the distribution tarballs that map to a module in the index. Sometimes a newer version of a distribution is released which removes a module. Until it is deleted via PAUSE, that old distribution will remain in the index. This module attemps to filter those old distributions from the local mirror.

METHODS

new( %options )

Overridden method which adds a sub to path_filters which will reject any dists which do not match the latest version from the 02packages.details.txt.gz index.

mirror_indices( )

Overridden method which parses 02packages.details.txt.gz and constructs the list of the latest version of each distribution.
