+# Gem::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 Gem::URI schemes.
+# * Flexibility to have an alternate Gem::URI::Parser (or just different patterns
+#   and regexp's).
+#
+# == Basic example
+#
+#   require 'rubygems/vendor/uri/lib/uri'
+#
+#   uri = Gem::URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
+#   #=> #<Gem::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 Gem::URI
+#     class RSYNC < Generic
+#       DEFAULT_PORT = 873
+#     end
+#     register_scheme 'RSYNC', RSYNC
+#   end
+#   #=> Gem::URI::RSYNC
+#
+#   Gem::URI.scheme_list
+#   #=> {"FILE"=>Gem::URI::File, "FTP"=>Gem::URI::FTP, "HTTP"=>Gem::URI::HTTP,
+#   #    "HTTPS"=>Gem::URI::HTTPS, "LDAP"=>Gem::URI::LDAP, "LDAPS"=>Gem::URI::LDAPS,
+#   #    "MAILTO"=>Gem::URI::MailTo, "RSYNC"=>Gem::URI::RSYNC}
+#
