Determines whether a valid license file is present. This function may be called without a legitimate run-time license to determine whether it is safe to call any Lexichem TK functionality.

The ‘feature’ argument can be used to check for a valid license to Lexichem TK along with the following features: ‘python’, ‘java’, or ‘clr’ (for CSharp).

The ‘expdate’ argument can be used to obtain the expiration date of the current Lexichem TK license.
