.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Ref::Util::XS is the \s-1XS\s0 implementation of Ref::Util, which provides several
functions to help identify references in a more convenient way than the
usual approach of examining the return value of \f(CW\*(C`ref\*(C'\fR.
.PP
You should use Ref::Util::XS by installing Ref::Util itself: if the system
you install it on has a C compiler available, \f(CW\*(C`Ref::Util::XS\*(C'\fR will be
installed and used automatically, providing a significant speed boost to
everything that uses \f(CW\*(C`Ref::Util\*(C'\fR.
.PP
See Ref::Util for full documentation of the available functions.
