+# - Find GNU gettext tools
+# This module looks for the GNU gettext tools. This module defines the 
+# following values:
+#  GETTEXT_MSGMERGE_EXECUTABLE: the full path to the msgmerge tool.
+#  GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
+#  GETTEXT_FOUND: True if gettext has been found.
+#
+# Additionally it provides the following macros:
+# GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ... fileN )
+#    This will create a target "translations" which will convert the 
+#    given input po files into the binary output mo file. If the 
+#    ALL option is used, the translations will also be created when
+#    building the default target.
+# GETTEXT_PROCESS_POT( <potfile> [ALL] [INSTALL_DESTINATION <destdir>] <lang1> <lang2> ... )
+#     Process the given pot file to mo files.
+#     If INSTALL_DESTINATION is given then automatically install rules will be created,
+#     the language subdirectory will be taken into account (by default use share/locale/).
+#     If ALL is specified, the pot file is processed when building the all traget.
+#     It creates a custom target "potfile".
+#
+# GETTEXT_PROCESS_PO_FILES(<lang> [ALL] [INSTALL_DESTINATION <dir>] <po1> <po2> ...)
+#     Process the given po files to mo files for the given language.
+#     If INSTALL_DESTINATION is given then automatically install rules will be created,
+#     the language subdirectory will be taken into account (by default use share/locale/).
+#     If ALL is specified, the po files are processed when building the all traget.
+#     It creates a custom target "pofiles".
