 * Root profiler interface.
 *
 * Profiler classes are expected to provide either a non-arg constructor,
 * or a constructor accepting single String argument, as the option line.
 * The treatment of option line is unspecified, and can be handled in
 * profiler-specific way. Profiler constructors can throw
 * {@link org.openjdk.jmh.profile.ProfilerException} if profiler cannot
 * operate, either because of misconfiguration, or help message requested.
 * The message in {@link org.openjdk.jmh.profile.ProfilerException} should
 * clearly articulate the reason.
 *
 * 
Profilers normally implement one of the subinterfaces.
