+# FindIntl
+# --------
+#
+# Find the Gettext libintl headers and libraries.
+#
+# This module reports information about the Gettext libintl
+# installation in several variables.  General variables::
+#
+#   Intl_FOUND - true if the libintl headers and libraries were found
+#   Intl_INCLUDE_DIRS - the directory containing the libintl headers
+#   Intl_LIBRARIES - libintl libraries to be linked
+#
+# The following cache variables may also be set::
+#
+#   Intl_INCLUDE_DIR - the directory containing the libintl headers
+#   Intl_LIBRARY - the libintl library (if any)
+#
+# .. note::
+#   On some platforms, such as Linux with GNU libc, the gettext
+#   functions are present in the C standard library and libintl
+#   is not required.  ``Intl_LIBRARIES`` will be empty in this
+#   case.
+#
+# .. note::
+#   If you wish to use the Gettext tools (``msgmerge``,
+#   ``msgfmt``, etc.), use :module:`FindGettext`.
