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