- dnl @synopsis AC_CHECK_CLASS
- dnl
- dnl AC_CHECK_CLASS tests the existence of a given Java class, either in
- dnl a jar or in a '.class' file.
- dnl
- dnl *Warning*: its success or failure can depend on a proper setting of
- dnl the 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.
