usage: perlgp-sample-pop.pl [ 0.1 ] | less (runs inside experiment directory)
Samples a random fraction (default 0.1, but you can give a different value on the command line) of the Population and prints the Perl code to STDOUT. It can be useful to pipe the output through grep and sort to give you an idea of what are the common ``genes'' (lines of code) in your gene pool.
