When creating a new client, the only pieces of information that are required are the name of the client and its root. The name is given upon invocation, but the workspace root normally has to be specified in the creation form or automatically generated by sed. However, you can take advantage of the fact that the workspace root is set, by default, to the directory where the client creation takes place.

Change to the proper directory.
Note: This method creates a client specification with the default client view mappings for the user.
