# SYNOPSIS
#
#   AC_TRY_RUN_JAVA
#
# DESCRIPTION
#
#   AC_TRY_RUN_JAVA attempt to compile and run user given source.
#
#   *Warning*: its success or failure can depend on a proper setting of the
#   CLASSPATH env. variable.
#
#   Note: This is part of the set of autoconf M4 macros for Java programs.
#   It is VERY IMPORTANT that you download the whole set, some macros depend
#   on other. Unfortunately, the autoconf archive does not support the
#   concept of set of macros, so I had to break it for submission. The
#   general documentation, as well as the sample configure.in, is included
#   in the AC_PROG_JAVA macro.
