   7 # SYNOPSIS
   8 #
   9 #   AX_PROG_JAR
  10 #
  11 # DESCRIPTION
  12 #
  13 #   AX_PROG_JAR tests for an existing jar program. It uses the environment
  14 #   variable JAR then tests in sequence various common jar programs.
  15 #
  16 #   If you want to force a specific compiler:
  17 #
  18 #   - at the configure.in level, set JAR=yourcompiler before calling
  19 #   AX_PROG_JAR
  20 #
  21 #   - at the configure level, setenv JAR
  22 #
  23 #   You can use the JAR variable in your Makefile.in, with @JAR@.
  24 #
  25 #   Note: This macro depends on the autoconf M4 macros for Java programs. It
  26 #   is VERY IMPORTANT that you download that whole set, some macros depend
  27 #   on other. Unfortunately, the autoconf archive does not support the
  28 #   concept of set of macros, so I had to break it for submission.
  29 #
  30 #   The general documentation of those macros, as well as the sample
  31 #   configure.in, is included in the AX_PROG_JAVA macro.
