/*
* call-seq:
* Signal.trap( signal, proc ) => obj
* Signal.trap( signal, command ) => obj
* Signal.trap( signal ) {| | block } => obj
*
* Specifies the handling of signals. The first parameter is a signal
* name (a string such as ``SIGALRM'', ``SIGUSR1'', and so on) or a
* signal number. The characters ``SIG'' may be omitted from the
* signal name. The command or block specifies code to be run when the
* signal is raised. If the command is the string ``IGNORE'' or
* ``SIG_IGN'', the signal will be ignored. If the command is
* ``DEFAULT'' or ``SIG_DFL'', the Ruby's default handler
* will be invoked. If the command is ``EXIT'', the script will be
* terminated by the signal. Otherwise, the given command or block
* will be run.
* signal is raised.
* If the command is the string ``IGNORE'' or ``SIG_IGN'', the signal
* will be ignored.
* If the command is ``DEFAULT'' or ``SIG_DFL'', the Ruby's default handler
* will be invoked.
* If the command is ``EXIT'', the script will be terminated by the signal.
* If the command is ``SYSTEM_DEFAULT'', the operating system's default
* handler will be invoked.
* Otherwise, the given command or block will be run.
* The special signal name ``EXIT'' or signal number zero will be
* invoked just prior to program termination.
* trap returns the previous handler for the given signal.
