28 | ;;; Commentary: | |
29 | ;;; This Package provides a set of functions to use the output of the | |
30 | ;;; cross reference capabilities of the GNAT Ada compiler | |
31 | ;;; for lookup and completion in Ada mode. | |
32 | ;;; | |
797aab3c | 33 | ;;; If a file *.`adp' exists in the ada-file directory, then it is |
ced16f5d | 34 | ;;; read for configuration informations. It is read only the first |
797aab3c GM |
35 | ;;; time a cross-reference is asked for, and is not read later. |
36 | ||
37 | ;;; You need Emacs >= 20.2 to run this package | |
