25 | ;; | |
26 | ;; Provide a simple user facing API to finding symbol references. | |
27 | ;; | |
28 | ;; This UI will is the base of some refactoring tools. For any | |
29 | ;; refactor, the user will execture `semantic-symref' in a tag. Once | |
30 | ;; that data is collected, the output will be listed in a buffer. In | |
31 | ;; the output buffer, the user can then initiate different refactoring | |
32 | ;; operations. | |
33 | ;; | |
34 | ;; NOTE: Need to add some refactoring tools. | |
