For example, alias value always must follow 'alias'. options accepts a combination of the following values. 'alias' Specifies that you want to assign another name to the shared library. If you specify an alias, always use the alias to refer to the shared library. alias value Specifies the alias name you want to assign to the shared library. alias value is a string.
