+//!
+//! These tests are based on `fork()` and `exec()`. The parent process is able
+//! to communicate with the child in the same manner as a base-class
+//! Multiprocess parent. The read and write pipes appear in the child process on
+//! stdin and stdout, respectively.
+//!
+//! Subclasses are expected to implement the parent in the same was as a
+//! base-class Multiprocess parent. The child must be implemented in an
+//! executable to be set by SetChildCommand().

+  //! \brief Sets the command to `exec()` in the child.
+  //!
+  //! This method must be called before the test can be Run().
+  //!
+  //! \param[in] command The executable’s pathname.
+  //! \param[in] arguments The command-line arguments to pass to the child

+  //!     as \a command is implicitly used as `argv[0]`. This argument may be
