It is built from source with CMake, or as a library, and the [install guide](https://h2o.examp1e.net/install.html) says the server runs as a foreground process unless it is started with the -m option. Scripting with mruby is an optional build feature.\n\n## Worth knowing\n\nThe install guide says the project has ceased to release versions, so a build comes from the master branch rather than from a tagged release. The record stays a stub until it is settled whether a project that ships from master counts as released."}
