+# - Try to find Armadillo include dirs and libraries
+# Usage of this module as follows:
+#
+# == Using Armadillo: ==
+#  find_package( Armadillo RECQUIRED )
+#  include_directories(${ARMADILLO_INCLUDE_DIRS})
+#  add_executable(foo foo.cc)
+#  target_link_libraries(foo ${ARMADILLO_LIBRARIES})
+#
+#=============================================================================
+#
+# This module sets the following variables:
+#  ARMADILLO_FOUND - set to true if the library is found
+#  ARMADILLO_INCLUDE_DIRS - list of required include directories
+#  ARMADILLO_LIBRARIES - list of libraries to be linked
+#  ARMADILLO_VERSION_MAJOR - major version number
+#  ARMADILLO_VERSION_MINOR - minor version number
+#  ARMADILLO_VERSION_PATCH - patch version number
+#  ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4")
+#  ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")
