| 11 | # DESCRIPTION | |
| 12 | # | |
| 13 | # Internal use ONLY. | |
| 14 | # | |
| 15 | # Note: This is part of the set of autoconf M4 macros for Java programs. | |
| 16 | # It is VERY IMPORTANT that you download the whole set, some macros depend | |
| 17 | # on other. Unfortunately, the autoconf archive does not support the | |
| 18 | # concept of set of macros, so I had to break it for submission. The | |
| 19 | # general documentation, as well as the sample configure.in, is included | |
| 20 | # in the AX_PROG_JAVA macro. | |
