Adding a use message

Adding a use message to your application lets users receive an instant online reminder for command-line arguments and basic usage simply by typing use app_name.

Use messages are stored in plain text files, typically named app_name.use, and are located in the root directories of your projects. For example, if you had the nodetime project open, its message file would be nodetime.use. This convention lets the recursive Makefile system automatically find your use message.

For information about writing use messages, see usemsg in the Utilities Reference.
