+# SYNOPSIS
+#
+# AX_CHECK_JAVA_PLUGIN(<shell-variable>)
+#
+# DESCRIPTION
+#
+# This macro sets <shell-variable> to empty on failure and to a compatible
+# version of plugin.jar otherwise. Directories searched are /usr/java/*
+# and /usr/local/java/*, which are assumed to be j{dk,re} installations.
+# Apply the shell variable as you see fit. If sun changes things so
+# <jre>/lib/plugin.jar is not the magic file it will stop working.
+#
+# This macro assumes that unzip, zipinfo or pkzipc is available (and can
+# list the contents of the jar archive). The first two are assumed to work
+# similarly enough to the infozip versisonms. The pkzipc version is
+# assumed to work if I undertstand the documentation on pkware's site but
+# YMMV. I do not have access to pwkware's version to test it.
