+# frozen_string_literal: false
+# Bundler::URI is a module providing classes to handle Uniform Resource Identifiers
+# (RFC2396[http://tools.ietf.org/html/rfc2396]).
+#
+# == Features
+#
+# * Uniform way of handling URIs.
+# * Flexibility to introduce custom Bundler::URI schemes.
+# * Flexibility to have an alternate Bundler::URI::Parser (or just different patterns
+#   and regexp's).
+#
+# == Basic example
+#
+#   require 'bundler/vendor/uri/lib/uri'
+#
+#   uri = Bundler::URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
+#   #=> #<Bundler::URI::HTTP http://foo.com/posts?id=30&limit=5#time=1305298413>
+#
+#   uri.scheme    #=> "http"
+#   uri.host      #=> "foo.com"
+#   uri.path      #=> "/posts"
+#   uri.query     #=> "id=30&limit=5"
+#   uri.fragment  #=> "time=1305298413"
+#
+#   uri.to_s      #=> "http://foo.com/posts?id=30&limit=5#time=1305298413"
+#
+# == Adding custom URIs
+#
+#   module Bundler::URI
+#     class RSYNC < Generic
+#       DEFAULT_PORT = 873
+#     end
+#     @@schemes['RSYNC'] = RSYNC
+#   end
+#   #=> Bundler::URI::RSYNC
+#
+#   Bundler::URI.scheme_list
+#   #=> {"FILE"=>Bundler::URI::File, "FTP"=>Bundler::URI::FTP, "HTTP"=>Bundler::URI::HTTP,
+#   #    "HTTPS"=>Bundler::URI::HTTPS, "LDAP"=>Bundler::URI::LDAP, "LDAPS"=>Bundler::URI::LDAPS,
+#   #    "MAILTO"=>Bundler::URI::MailTo, "RSYNC"=>Bundler::URI::RSYNC}
+#
+#   uri = Bundler::URI("rsync://rsync.foo.com")
+#   #=> #<Bundler::URI::RSYNC rsync://rsync.foo.com>
+#
+# == RFC References
+#
+# A good place to view an RFC spec is http://www.ietf.org/rfc.html.
+#

+    # The headers can be supplied as a pre-encoded string, such as

+    # like <code>[['subject', 'subscribe'], ['cc', 'address']]</code>.
