a data structure describing the opcode, operands, and flags.  The encoder takes
a similar data structure and produces a sequence of 1 to 15 bytes.  Disassembly
is essentially a printing pass on the data structure.

The library and development files are under the @code{lib} output, with a
family of command line utility wrappers in the default output.  Each of the cli
tools is named like @code{xed*}.  Documentation for the cli tools is sparse, so
this is a case where ``the code is the documentation.''")
