dnl @synopsis AC_CHECK_RQRD_CLASS
dnl
dnl AC_CHECK_RQRD_CLASS tests the existence of a given Java class,
dnl either in a jar or in a '.class' file and fails if it doesn't
dnl exist. Its success or failure can depend on a proper setting of the
dnl CLASSPATH env. variable.
dnl
dnl Note: This is part of the set of autoconf M4 macros for Java
dnl programs. It is VERY IMPORTANT that you download the whole set,
dnl some macros depend on other. Unfortunately, the autoconf archive
dnl does not support the concept of set of macros, so I had to break it
dnl for submission. The general documentation, as well as the sample
dnl configure.in, is included in the AC_PROG_JAVA macro.
