compare.rb
# Compares if a version is greater than other.
Gem::Version.new('2.1.15') > Gem::Version.new('1.14.1')
# => true
# It supports any number of minor versions
Gem::Version.new('2.0.0.1') < Gem::Version.new('2.0.1')
# => true
# And it deals with empty strings and nil values
Gem::Version.new('') < Gem::Version.new('2.0.1')
