-# - Find Pixman
-# Find the Pixman libraries
+# - Try to find the PIXMAN library
+# Once done this will define
 #
-#  This module defines the following variables:
-#     PIXMAN_FOUND        - true if PIXMAN_INCLUDE_DIR & PIXMAN_LIBRARY are found
-#     PIXMAN_LIBRARIES    - Set when PIXMAN_LIBRARY is found
-#     PIXMAN_INCLUDE_DIRS - Set when PIXMAN_INCLUDE_DIR is found
-#
-#     PIXMAN_INCLUDE_DIR  - where to find pixman.h, etc.
-#     PIXMAN_LIBRARY      - the Pixman library
+#  PIXMAN_ROOT_DIR - Set this variable to the root installation of PIXMAN
 #
+# Read-Only variables:
+#  PIXMAN_FOUND - system has the PIXMAN library
+#  PIXMAN_INCLUDE_DIR - the PIXMAN include directory
+#  PIXMAN_LIBRARIES - The libraries needed to use PIXMAN
+#  PIXMAN_VERSION - This is set to $major.$minor.$revision (eg. 0.9.8)
