# A ComposedSet allows multiple sets to be queried like a single set.
#
# To create a composed set with any number of sets use:
#
#   Gem::Resolver.compose_sets set1, set2
#
# This method will eliminate nesting of composed sets.

  # Creates a new ComposedSet containing +sets+.  Use
  # Gem::Resolver::compose_sets instead.

  # Sets the remote network access for all composed sets.
