x11-links creates a shadow directory of symbolic links for X11 headers and libraries to ${X11BASE} under ${PREFIX}/share/x11-links. It is intended for use by buildlink code to cleanly separate out the true X11 code files from any installed X11 package code files. The X11 hierarchies supported are: XFree86-3.3.x XFree86-4.0.x XFree86-4.1.x XFree86-4.2.x XFree86-4.3.x Xorg-6.8.x Xorg-6.9
