This SlackBuild intentionally targets watchman 4.9.0.

Newer versions introduce additional dependencies that are not
currently available or practical on Slackware 15.0.

Version 4.9.0 provides stable functionality and is sufficient
for common use cases such as React Native development.

No daemon setup is required. The service is started automatically
by client applications when needed.

Optional: For large projects, you may need to increase inotify limits.
See upstream documentation for details.
