| 6 | # |
| 7 | # AX_CHECK_CLASS |
| 8 | # |
| 9 | # DESCRIPTION |
| 10 | # |
| 11 | # AX_CHECK_CLASS tests the existence of a given Java class, either in a |
| 12 | # jar or in a '.class' file. |
| 13 | # |
| 14 | # *Warning*: its success or failure can depend on a proper setting of the |
| 15 | # CLASSPATH env. variable. |
| 16 | # |
| 17 | # Note: This is part of the set of autoconf M4 macros for Java programs. |
| 18 | # It is VERY IMPORTANT that you download the whole set, some macros depend |
| 19 | # on other. Unfortunately, the autoconf archive does not support the |
| 20 | # concept of set of macros, so I had to break it for submission. The |
| 21 | # general documentation, as well as the sample configure.in, is included |
| 22 | # in the AX_PROG_JAVA macro. |
