Robert Helgesson 7ca412a2fa nix-generate-from-cpan: fix core module detection
This makes the detection of core modules a bit more robust by checking
the module inclusion in a pure Perl interpreter. This ensures that any
extra path in the `nix-generate-from-cpan` script's `PERL5LIB` does not
affect the generated package expression.

Robert Helgesson c90c30dd1e nix-generate-from-cpan: large refactor
This commit includes a substantial refactoring of
`nix-generate-from-cpan`. This somewhat simplifies the code through the
use of the CPAN::Meta module while adding the following features:

 - The program now takes an optional maintainer on the command line that
   is subsequently added into the generated package.

 - An attempt is made to convert the license specified inside the
   META.json or META.yaml file to a license in `stdenv.lib.licenses`.

 - An attempt is made to disambiguate attribute names of packages whose
   name is a reserved word in Nix.

 - Write logging output using Log::Log4perl.

 - Print module RSS feed URL. The RSS feed, hosted by MetaCPAN, can be
   used to track updates to the module.

Eelco Dolstra 97a2de297e Fix various Perl packages
Perl 5.20 removed some modules, in particular Module::Pluggable. So
now other modules need to get it from CPAN.

Eelco Dolstra 629daa2102 Rewrite the CPAN generator to Perl
Also:

- It's now installable by doing "nix-env -i nix-generate-from-cpan".

- It maps dependencies to the correct attribute (e.g. HTML::HeadParser
  is mapped to HTMLParser).

- It automatically selects buildPerlPackage or buildPerlModule.

- It's documented in the manual.
