# SYNOPSIS
#
#   AX_CHECK_JUNIT
#
# DESCRIPTION
#
#   AX_CHECK_JUNIT tests the availability of the Junit testing framework,
#   and set some variables for conditional compilation of the test suite by
#   automake.
#
#   If available, JUNIT is set to a command launching the text based user
#   interface of Junit, @JAVA_JUNIT@ is set to $JAVA_JUNIT and @TESTS_JUNIT@
#   is set to $TESTS_JUNIT, otherwise they are set to empty values.
#
#   You can use these variables in your Makefile.am file like this :
#
#    # Some of the following classes are built only if junit is available
#    JAVA_JUNIT  = Class1Test.java Class2Test.java AllJunitTests.java
#
#    noinst_JAVA = Example1.java Example2.java @JAVA_JUNIT@
#
#    EXTRA_JAVA  = $(JAVA_JUNIT)
#
#    TESTS_JUNIT = AllJunitTests
#
#    TESTS       = StandaloneTest1 StandaloneTest2 @TESTS_JUNIT@
#
#    EXTRA_TESTS = $(TESTS_JUNIT)
#
#    AllJunitTests :
#       echo "#! /bin/sh" > $@
#       echo "exec @JUNIT@ my.package.name.AllJunitTests" >> $@
#       chmod +x $@
