+# URI is a module providing classes to handle Uniform Resource Identifiers
+# (RFC2396[http://tools.ietf.org/html/rfc2396])
 #
-# URI support for Ruby
+# == Features
+#
+# * Uniform handling of handling URIs
+# * Flexibility to introduce custom URI schemes
+# * Flexibility to have an alternate URI::Parser (or just different patterns
+#   and regexp's)
+#
+# == Basic example
+#
+#   require 'uri'
+#
+#   uri = URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
+#   #=> #<URI::HTTP:0x00000000b14880
+#         URL: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 URI
+#     class RSYNC < Generic
+#       DEFAULT_PORT = 873
+#     end
+#     @@schemes['RSYNC'] = RSYNC
+#   end
+#   #=> URI::RSYNC
+#
+#   URI.scheme_list
+#   #=> {"FTP"=>URI::FTP, "HTTP"=>URI::HTTP, "HTTPS"=>URI::HTTPS,
+#        "LDAP"=>URI::LDAP, "LDAPS"=>URI::LDAPS, "MAILTO"=>URI::MailTo,
+#        "RSYNC"=>URI::RSYNC}
+#
+#   uri = URI("rsync://rsync.foo.com")
+#   #=> #<URI::RSYNC:0x00000000f648c8 URL:rsync://rsync.foo.com>
+#
