 dnl A sample configure.in is at the end of this file. Each macro is
 dnl documented by comments before its definition. Here is a summary:
 dnl
 dnl AX_PROG_JAVAC: finds a Java compiler
 dnl AX_PROG_JAVA: finds a Java virtual machine
 dnl AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!)
 dnl AX_CHECK_RQRD_CLASS: finds if we have the given class and stops otherwise


 dnl AX_PROG_JAVAC tests an existing Java compiler. It uses the environment
 dnl variable JAVAC then tests in sequence various common Java compilers. For
 dnl political reasons, it starts with the free ones.
 dnl If you want to force a specific compiler:
 dnl  - at the configure.in level, set JAVAC=yourcompiler before calling
 dnl    AX_PROG_JAVAC
 dnl  - at the configure level, setenv JAVAC
 dnl You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
 dnl
 dnl *Warning*: its success or failure can depend on a proper setting of the
 dnl CLASSPATH env. variable.
 dnl
 dnl TODO: allow to exclude compilers (rationale: most Java programs cannot compile
 dnl with some compilers like guavac).

 ])


 dnl AX_PROG_JAVA tests an existing Java virtual machine. It uses the
 dnl environment variable JAVA then tests in sequence various common Java
 dnl virtual machines. For political reasons, it starts with the free ones.
 dnl You *must* call [AX_PROG_JAVAC] before.
 dnl If you want to force a specific VM:
 dnl  - at the configure.in level, set JAVA=yourvm before calling AX_PROG_JAVA
 dnl  - at the configure level, setenv JAVA
 dnl You can use the JAVA variable in your Makefile.in, with @JAVA@.
 dnl
 dnl *Warning*: its success or failure can depend on a proper setting of the
 dnl CLASSPATH env. variable.
 dnl
 dnl TODO: allow to exclude virtual machines (rationale: most Java programs
 dnl cannot run with some VM like kaffe).
 dnl
