===========
Perl
===========

Perl is available as a software module. No additional perl modules have been
installed. Installing local modules using local::lib with cpanm is the
preferred method. Here is an example to install and test Math::CDF::

 module load perl
 eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)
 cpanm Math::CDF
 perl -e "require Math::CDF"

To have the appropriate environment available during login, it is recommended
to put these lines in the $HOME/.bashrc::

 module load perl
 [ $SHLVL -eq 1 ] && eval "$(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)"

Additional details on local::lib can be in the `local::lib documentation <http://search.cpan.org/perldoc/local::lib>`_.
