# Provides better documentation in the specs by
# naming sets of features that work together as
# a whole. Examples include :encoding, :fiber,
# :continuation, :fork.
#
# Usage example:
#
# with_feature :encoding do
# # specs for a method that provides aspects
# # of the encoding feature
# end
#
# Multiple features must all be enabled for the
# guard to run:
#
# with_feature :one, :two do
# # these specs will run if features :one AND
# # :two are enabled.
# end
#
# The implementation must explicitly enable a feature
# by adding code like the following to the .mspec
# configuration file:
#
# MSpec.enable_feature :encoding
#
