You can omit all Open Source Software from a TrulyNatural binary by:

- Compiling with `-DSNSR_OMIT_OSS_COMPONENTS` (see [Compile-time macros § SNSR_OMIT_OSS_COMPONENTS](https://doc.sensory.com/tnl/7.8/api/compile-macros.md#snsr-omit-oss-components))
- or by using custom initialization with models that do not require
  these components. See [model:ids](https://doc.sensory.com/tnl/7.8/api/setting-keys/runtime.md#modelids), [snsr-edit](https://doc.sensory.com/tnl/7.8/tools/snsr-edit.md#snsr-edit), and
  [reduce code size](https://doc.sensory.com/tnl/7.8/faq.md#reduce-code-size).

Query [oss-components](https://doc.sensory.com/tnl/7.8/api/setting-keys/library-information.md#oss-components) to determine which of these modules are linked
into an application.
