+# @ebuild-function ejunit
+#
+# Junit wrapper function. Makes it easier to run the tests and checks for
+# dev-java/junit in DEPEND. Launches the tests using junit.textui.TestRunner.
+#
+# Examples:
+# ejunit -cp build/classes org.blinkenlights.jid3.test.AllTests
+# ejunit org.blinkenlights.jid3.test.AllTests
+#
+# @param $1 - -cp or -classpath
+# @param $2 - classpath, junit gets appended
+# @param $@ - the rest of the parameters are passed to java
+# ------------------------------------------------------------------------------
