1 The Mercurial wire protocol is a request-response based protocol

     2 with multiple wire representations.

     4 Each request is modeled as a command name, a dictionary of arguments, and

     5 optional raw input. Command arguments and their types are intrinsic

     6 properties of commands. So is the response type of the command. This means

     7 clients can't always send arbitrary arguments to servers and servers can't

     8 return multiple response types.

    10 The protocol is synchronous and does not support multiplexing (concurrent

    11 commands).
