+# - Try to find readline include dirs and libraries 
+#
+# Usage of this module as follows:
+#
+#     find_package(Readline)
+#
+# Variables used by this module, they can change the default behaviour and need
+# to be set before calling find_package:
+#
+#  Readline_ROOT_DIR         Set this variable to the root installation of
+#                            readline if the module has problems finding the
+#                            proper installation path.
+#
+# Variables defined by this module:
+#
+#  READLINE_FOUND            System has readline, include and lib dirs found
+#  GNU_READLINE_FOUND        Version of readline found is GNU readline, not libedit!
+#  LIBEDIT_FOUND             Version of readline found is libedit, not GNU readline!
+#  Readline_INCLUDE_DIR      The readline include directories. 
+#  Readline_LIBRARY          The readline library.
+#  GNU_READLINE_LIBRARY      The GNU readline library or empty string.
+#  LIBEDIT_LIBRARY           The libedit library or empty string.
