@node Protocol
@unnumbered Protocol

Protocol is very simple: two
@url{https://en.wikipedia.org/wiki/Netstring, netstring}s are sent over TCP.
First one holds desired filename extension, without the leading dot, up to 9
characters long. Second one is the paste data itself.

@example
  "hello world", no explicit extension => 0:,11:hello world,
"http://example.com/", "url" extension => 3:url,18:http://example.com,
@end example
