This module provides a convenient way to sort on several fields To install, do the usual dance: less Makefile.PL less lib/Sort/MultipleFields.pm less t/* those being to ensure that I'm not being evil. then do this to install the module: perl Makefile.PL make make test make install (you may need to do this as root) or to install it and all its dependencies from the CPAN: sudo perl -MCPAN -e 'install qw(Sort::MultipleFields)'
