Net::Calais provides a Perl interface to the OpenCalais platform. See http://www.opencalais.com/ for more information.
Net::Calais may be installed through the CPAN shell in the usual manner. Typically:
$ perl -MCPAN -e 'install Net::Calais'
You can also read this README from the CPAN shell:
$ perl -MCPAN -e shell
cpan> readme Net::Calais
And you can install the component from the CPAN prompt as well:
cpan> install Net::Calais
This module may also be installed manually. Its distribution is available from the author's CPAN directory, <ftp://ftp.cpan.org/pub/CPAN/authors/id/A/AA/AAR/>, or a similarly named directory at your favorite CPAN mirror.
Downloading and unpacking the distribution are left as exercises for the reader. To build and test it:
perl Makefile.PL
make test
When you're ready to install the component:
make install
It should now be ready to use.
Thanks for reading!
