-// pkt-line Format
-// ---------------
-//
-// Much (but not all) of the payload is described around pkt-lines.
-//
-// A pkt-line is a variable length binary string.  The first four bytes
-// of the line, the pkt-len, indicates the total length of the line,
-// in hexadecimal.  The pkt-len includes the 4 bytes used to contain
-// the length's hexadecimal representation.
-//
-// A pkt-line MAY contain binary data, so implementors MUST ensure
-// pkt-line parsing/formatting routines are 8-bit clean.
-//
-// A non-binary line SHOULD BE terminated by an LF, which if present
-// MUST be included in the total length.
-//
-// The maximum length of a pkt-line's data component is 65520 bytes.
-// Implementations MUST NOT send pkt-line whose length exceeds 65524
-// (65520 bytes of payload + 4 bytes of length data).
-//
-// Implementations SHOULD NOT send an empty pkt-line ("0004").
-//
-// A pkt-line with a length field of 0 ("0000"), called a flush-pkt,
-// is a special case and MUST be handled differently than an empty
-// pkt-line ("0004").
-//
-// ----
-//   pkt-line     =  data-pkt / flush-pkt
-//
-//   data-pkt     =  pkt-len pkt-payload
-//   pkt-len      =  4*(HEXDIG)
-//   pkt-payload  =  (pkt-len - 4)*(OCTET)
-//
-//   flush-pkt    = "0000"
-// ----
-//
-// Examples (as C-style strings):
-//
-// ----
-//   pkt-line          actual value
-//   ---------------------------------
-//   "0006a\n"         "a\n"
-//   "0005a"           "a"
-//   "000bfoobar\n"    "foobar\n"
-//   "0004"            ""
