From McXtrace version 1.3, MCPL plugins are shipped as part of the McXtrace
Component distribution. Please refer to the following McXtrace instrument files
in the examples/ directory of that distribution for demonstrations of how to
enable the relevant components:

  examples/Test_MCPL_input.instr
  examples/Test_MCPL_output.instr

Additionally, users of McXtrace automatically have access to the mcpltool
command.

Further instructions are also available at https://mctools.github.io/mcpl/.
