== The APEX CLI Editor
The CLI Editor allows to define policies from the command line.
The application uses a simple language and supports all elements of an APEX policy.
It can be used in to different ways:

- non-interactive, specifying a file with the commands to create a policy
- interactive, using the editors CLI to create a policy

When a policy is fully specified, the editor will generate the APEX core policy specification in JSON.
This core specification is called the policy model in the APEX engine and can be used directly with the APEX engine.

On UNIX and Cygwin systems use:

- `apexCLIEditor.sh` - simply starts the CLI editor, arguments to the script determine the mode of the editor
- `apexApps.sh cli-editor` - simply starts the CLI editor, arguments to the script determine the mode of the editor

On Windows systems use:

- `apexCLIEditor.bat` - simply starts the CLI editor, arguments to the script determine the mode of the editor
- `apexApps.bat cli-editor` - simply starts the CLI editor, arguments to the script determine the mode of the editor
