LispWorks is protected against unauthorized copying and use by a simple key mechanism. LispWorks will not start up until it finds a file containing a valid key.
The image looks for a file lwlicense in the following places, in order:
Library/lib/7-0-0-0/config subdirectory of the LispWorks installation directory
When the file lwlicense is found, it must contain a valid key for the current machine. If you try to run LispWorks without a valid key, a message will be printed to the console reporting that no valid key was found, and LispWorks will exit.
