-// Options
-
-// Each of the definitions above may have "options" attached.  These are
-// just annotations which may cause code to be generated slightly differently
-// or may contain hints for code that manipulates protocol messages.
-//
-// Clients may define custom options as extensions of the *Options messages.
-// These extensions may not yet be known at parsing time, so the parser cannot
-// store the values in them.  Instead it stores them in a field in the *Options
-// message called uninterpreted_option. This field must have the same name
-// across all *Options messages. We then use this field to populate the
-// extensions when we build a descriptor, at which point all protos have been
-// parsed and so all extensions are known.
-//
-// Extension numbers for custom options may be chosen as follows:
-// * For options which will only be used within a single application or
-//   organization, or for experimental options, use field numbers 50000
-//   through 99999.  It is up to you to ensure that you do not use the
-//   same number for multiple options.
-// * For options which will be published and used publicly by multiple
-//   independent entities, e-mail kenton@google.com to reserve extension
-//   numbers.  Simply tell me how many you need and I'll send you back a
-//   set of numbers to use -- there's no need to explain how you intend to
-//   use them.  If this turns out to be popular, a web service will be set up
-//   to automatically assign option numbers.

+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+//   organization, or for experimental options, use field numbers 50000
+//   through 99999.  It is up to you to ensure that you do not use the
+//   same number for multiple options.
+// * For options which will be published and used publicly by multiple
+//   independent entities, e-mail kenton@google.com to reserve extension
+//   numbers.  Simply tell me how many you need and I'll send you back a
