+# This module finds if CABLE is installed and determines where the
+# include files and libraries are.  This code sets the following variables:
+#
+#  CABLE              = the full path to the cable executable
+#  CABLE_TCL_LIBRARY  = the full path to the Tcl wrapper facility library
+#  CABLE_ROOT         = the full path to the root of the cable installation
+#
+#  To build Tcl wrappers, you should add shared library and link it to
+#  ${CABLE_TCL_LIBRARY}.  You should also add ${CABLE_ROOT}/include as
+#  an include directory.
+#
+
+# Use some tricks to find the cable executable relative to somewhere
+# in the system search path.  CMake will collapse the relative paths
+# automatically.
