   7 #   AX_CHECK_RQRD_CLASS
   8 #
   9 # DESCRIPTION
  10 #
  11 #   AX_CHECK_RQRD_CLASS tests the existence of a given Java class, either in
  12 #   a jar or in a '.class' file and fails if it doesn't exist. Its success
  13 #   or failure can depend on a proper setting of the CLASSPATH env.
  14 #   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.
