+# - Find Ragel executable and provides macros to generate custom build rules
+# The module defines the following variables:
+#
+#  RAGEL_EXECUTABLE - path to the ragel program
+#  RAGEL_VERSION - version of ragel
+#  RAGEL_FOUND - true if the program was found
+#
+# If ragel is found, the module defines the macros:
+#
+#  RAGEL_TARGET(<Name> INPUTS <inputs> OUTPUT <output>
+#              [COMPILE_FLAGS <string>] [DEPENDS <depends>])
+#
+# which will create  a custom rule to generate a state machine. <RagelInp> is
+# the path to a Ragel file. <CodeOutput> is the name of the source file
+# generated by ragel. If  COMPILE_FLAGS option is specified, the next
+# parameter is  added in the ragel  command line.
+#
+# The macro defines a set of variables:
+#  RAGEL_${Name}_DEFINED       - true is the macro ran successfully
+#  RAGEL_${Name}_INPUT         - The input source file, an alias for <RagelInp>
+#  RAGEL_${Name}_OUTPUT_SOURCE - The source file generated by ragel
+#  RAGEL_${Name}_OUTPUT_HEADER - The header file generated by ragel
+#  RAGEL_${Name}_OUTPUTS       - The sources files generated by ragel
+#  RAGEL_${Name}_COMPILE_FLAGS - Options used in the ragel command line
+#
+#  ====================================================================
+#  Example:
+#
+#   find_package(RAGEL) # or e.g.: find_package(RAGEL 6.6 REQUIRED)
+#   RAGEL_TARGET(MyMachine machine.rl ${CMAKE_CURRENT_BINARY_DIR}/machine.cc)
+#   add_executable(Foo main.cc ${RAGEL_MyMachine_OUTPUTS})
