5 | # SYNOPSIS | |
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. | |
