+# Synopsis:
+#
+#  scons-doc [OPTIONS] [.in files]
+#
+#   When no input files are given, the folder doc/user/* is searched for .in files.
+#
+# Available options:
+#
+#   -d, --diff            create examples for the .in file and output a unified
+#                         diff against the related .xml file
+#   -r, --run             create examples for the .in file, but do not change
+#                         any files
+#   -s, --simple_diff     use a simpler output for the diff mode (no unified
+#                         diff!)
+#   -u, --update          create examples for the .in file and update the
+#                         related .xml file
+#
 # This script looks for some SGML tags that describe SCons example
 # configurations and commands to execute in those configurations, and
