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)'
