d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe * Note: this implementation is _very_ experimental, and error handling
d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe * is far from complete.  Using it as a cgi or pipe process allows the
d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe * programmer to discover if facilities such as reliable piped logs
d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe * are working as expected, or answer operator prompts that would
d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe * otherwise be discarded by the service process.
d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe *
d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe * Also note the isservice detection semantics, which far exceed any
d15674e194392bfaedba1fe2fccc9297e4e20da6wrowe * mechanism we have discovered thus far.
