+# If set to TRUE, the following are also defined:
+#   ICONV_INCLUDE_DIRS  -  The directory where to find the header file
+#   ICONV_LIBRARIES  -  Where to find the library file
+#   ICONV_SECOND_ARGUMENT_IS_CONST  -  The second argument for iconv() is const
+#
+# For conveniance, these variables are also set. They have the same values
+# than the variables above.  The user can thus choose his/her prefered way
+# to write them.
