- Factory-Supplied Option Trees:
  - The following option trees are distributed with each NeXtMidas baseline and maintained by the framework manager:
    - DSP - Digital Signal Processing commands.
    - HWC - Hardware Control Functionality commands.
    - SYS - Shell code, infrastructure libraries, and commands that are fundamental to NeXtMidas operation
    - UCL - User-Contributed Library commands. (Not officially supported and subject to change without notice.)
- Caveats Regarding Changing the Factory-Supplied Option Trees:
  - If you change code or documentation files within these option trees, realize that your changes will be overwritten without warning the next time you update your baseline.
  - If changes are required to fix bugs or documentation errors, please send a copy of your modified files to the framework manager for review and possible inclusion in the next release
  - If you're changing command code to add new features, you are strongly encouraged to house your version in a locally-maintained option tree.
