Cliclick is short for "Command-Line Interface Click". It is a tiny shell / Terminal application that will emulate mouse and/or keyboard events such as moving the mouse, clicking, double-clicking, dragging with or without modifier keys, or typing text.
Hence, it is a tool for automating/scripting things that cannot otherwise be scripted (for instance, using AppleScript). Other than GUI Scripting, it does not require "Access for assistive devices" to be activated in the System Preferences.
Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
