+# - Find Java
+# This module finds if Java is installed and determines where the
+# include files and libraries are. This code sets the following
+# variables:
+#
+# Java_JAVA_EXECUTABLE = the full path to the Java runtime
+# Java_JAVAC_EXECUTABLE = the full path to the Java compiler
+# Java_JAVAH_EXECUTABLE = the full path to the Java header generator
+# Java_JAVADOC_EXECUTABLE = the full path to the Java documention generator
+# Java_JAR_EXECUTABLE = the full path to the Java archiver
+# Java_VERSION_STRING = Version of the package found (java version), eg. 1.6.0_12
+# Java_VERSION_MAJOR = The major version of the package found.
+# Java_VERSION_MINOR = The minor version of the package found.
+# Java_VERSION_PATCH = The patch version of the package found.
+# Java_VERSION_TWEAK = The tweak version of the package found (after '_')
+# Java_VERSION = This is set to: $major.$minor.$patch(.$tweak)
+#
+# The minimum required version of Java can be specified using the
+# standard CMake syntax, e.g. FIND_PACKAGE(Java 1.5)
+#
+# NOTE: ${Java_VERSION} and ${Java_VERSION_STRING} are not guaranteed to be
+# identical. For example some java version may return:
+# Java_VERSION_STRING = 1.5.0_17
+# and
+# Java_VERSION = 1.5.0.17
+#
+# another example is the Java OEM, with:
+# Java_VERSION_STRING = 1.6.0-oem
+# and
+# Java_VERSION = 1.6.0
+#
+# For these components the following variables are set:
+#
+# Java_FOUND - TRUE if all components are found.
+# Java_INCLUDE_DIRS - Full paths to all include dirs.
+# Java_LIBRARIES - Full paths to all libraries.
+# Java_<component>_FOUND - TRUE if <component> is found.
+#
+# Example Usages:
+# FIND_PACKAGE(Java)
+# FIND_PACKAGE(Java COMPONENTS Runtime)
+# FIND_PACKAGE(Java COMPONENTS Development)
+#
