A plugin that provides extra functionality to Fabrique build descriptions.
Plugins are written in C++ to provide functionality that simple shell commands don't express well. For instance, instead of parsing the output of sysctl(8) (turning a typed value into a string and back into a value according to expected type), a sysctl plugin can represent the underlying types correctly. The difference is: if a Fabrique description expects the wrong type, it can receive a type error rather than a syntactically-legal but logically-incorrect reinterpretation (e.g. "0").
