Last change on this file since 6b98325 was 6b98325, checked in by Richard Sanger <rsangerarj@…>, 6 years ago

Removes pconfig_input() and replaces trace_config() with trace_set_<option>

  • Removes trace_pconfig completely - only trace_set_hasher is left now in trace_config
  • Rework user configuration so this is no longer modified directly. Now we just apply it directly to a trace.
  • Many minor documentation fixes and additions
  • Property mode set to 100644
