##
# Gem::Server and allows users to serve gems for consumption by
# `gem --remote-install`.
#
# gem_server starts an HTTP server on the given port and serves the following:
# * "/" - Browsing of gem spec files for installed gems
# * "/specs.#{Gem.marshal_version}.gz" - specs name/version/platform index
# * "/latest_specs.#{Gem.marshal_version}.gz" - latest specs
# name/version/platform index
# * "/quick/" - Individual gemspecs
# * "/gems" - Direct access to download the installable gems
# * legacy indexes:
# * "/Marshal.#{Gem.marshal_version}" - Full SourceIndex dump of metadata
# for installed gems
# * "/yaml" - YAML dump of metadata for installed gems - deprecated
#
# == Usage
#
# gem_server = Gem::Server.new Gem.dir, 8089, false
# gem_server.run
#
#--
# TODO Refactor into a real WEBrick servlet to remove code duplication.
