+wx-config returns configuration information about the installed
+version of wxWindows. It may be used to query its version and
+installation directories and also retrieve the C and C++ compilers
+and linker which were used for its building and the corresponding
+flags.
+
+Ordinarily it should be installed to the appropriate system location
+along with the headers and library files, but it is also possible to
+use it to enable builds with an uninstalled wxWindows version for
+package building and bleeding edge developers. To do so, use it like
+this:
+
+\${wx_builddir}/wx-config --prefix=\${wx_srcdir} --exec-prefix=\${wx_builddir}
+
+Note that any other options supplied must come *after* the prefix
+specification for it to take effect.
