///   to a terminal (if any) instead of the environment in which the scripting language is being used.
/// - The \b lal.swig_redirect_standard_output_error() function turns on standard output/error redirection
///   for all LAL libraries; see <tt>SWIGLALAlpha.i</tt> for its definition. The current redirection state
///   is stored in the \c swig_lal_do_redirect_stdouterr variable.
/// - It is possible for a SWIG wrapper function to call another SWIG wrapper function (e.g. through
///   destructors), whereas standard output/error redirection should only happen once (within the outermost
///   SWIG wrapper function). The \c swig_lal_has_stdouterr_been_redirected variable indicates whether
///   redirection is already in place.
/// - The \b SWIGLAL_REDIRECT_STDOUTERR and \b SWIGLAL_RESTORE_OUTPUT_STDOUTERR hooks are inserted by an
///   \b %exception block (see below) and implement standard output/error redirection. These macros refer
///   to a locally saved value of \c swig_lal_do_redirect_stdouterr in case its value is changed by
///   \c $action (i.e. by a call to \b lal.swig_redirect_standard_output_error()). If the value of
//    \c swig_lal_has_stdouterr_been_redirected is true then redirection is already in place and these
//    macros do nothing.
/// - The common function \b swiglal_redirect_stdouterr() redirects standard output & error to temporary
///   files \c swiglal_tmp_stdout and \c swiglal_tmp_stderr respectively.
/// - The common function \b swiglal_restore_stdouterr() restores the system standard output & error.
/// - The scripting language-specific function \b swiglal_output_stdouterr() outputs the captured
///   standard output & error through the scripting language API in a way that is robust to any
///   redirections within the scripting language itself.
