sha1sum(1) is only common GNU systems, and it may be installed as gsha1sum on *BSDs. We'll also try using the openssl sha1 implementation, too. And finally, we'll provide our own Ruby sha1sum.rb implementation as a last resort. We go to great lengths to avoid our own Ruby version because we want to avoid putting too much trust in ourselves, our Ruby skills, and even the Ruby implementations. This is especially with regard to our knowledge and correct usage of Ruby 1.9 encoding support. It would actually be *easier* to only use sha1sum.rb and call it a day. We just choose to support SHA1 implementations provided by third parties if possible. Performance is not a factor since sha1sum.rb performance is very close to the C implementations.
