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