Creation of 'sf-create-public-PDK' for munging licences in text files. Not tested yet as I've got another build running on this machine, so submitting and kicking via Hudson.
#!perl -w
use strict;
# Sorts the input, removes duplicates, and outputs it
# Read it
my @content = <>;
# Sort it, and grep to remove duplicates
my $previous = "\n\n";
@content = grep {$_ ne $previous && ($previous = $_, 1) } sort @content;
# Write it
print @content;
