NAME

       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"
	 my $extension = $d->extension; # "tar.gz"
	 my $pathname  = $d->pathname;	# "authors/id/G/GB/GBARR/..."

	 my %prop = $d->properties;

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
