CPAN::DistnameInfo - Extract distribution name and version from a distribution filename

#SYNOPSIS

my $pathname = "authors/id/G/GB/GBARR/CPAN-DistnameInfo-0.02.tar.gz";

my $d = CPAN::DistnameInfo->new($pathname);

my $dist      = $d->dist;      # "CPAN-DistnameInfo"
my $version   = $d->version;   # "0.02"
my $maturity  = $d->maturity;  # "released"
my $filename  = $d->filename;  # "CPAN-DistnameInfo-0.02.tar.gz"
my $cpanid    = $d->cpanid;    # "GBARR"
my $distvname = $d->distvname; # "CPAN-DistnameInfo-0.02"

#DESCRIPTION

Many online services that are centered around CPAN attempt to associate multiple uploads by extracting a distribution name from the filename of the upload. For most distributions this is easy as they have used ExtUtils::MakeMaker or Module::Build to create the distribution, which results in a uniform name. But sadly not all uploads are created in this way.

CPAN::DistnameInfo uses heuristics that have been learnt by http://search.cpan.org/ to extract the distribution name and version from filenames and also report if the version is to be treated as a developer release

The constructor takes a single pathname, returning an object with the following methods

#cpanid: If the path given looked like a CPAN authors directory path, then this will be the the CPAN id of the author.
#dist: The name of the distribution
#distvname: The file name with any suffix and leading directory names removed
#filename: If the path given looked like a CPAN authors directory path, then this will be the path to the file relative to the detected CPAN author directory. Otherwise it is the path that was passed in.
#maturity: The maturity of the distribution. This will be either released or developer
#extension: The extension of the distribution, often used to denote the archive type (e.g. 'tar.gz')
#pathname: The pathname that was passed to the constructor when creating the object.
#properties: This will return a list of key-value pairs, suitable for assigning to a hash, for the known properties.
#version: The extracted version
