+Configuring with libjvm
+-----------------------
+
+  To determine the location of the required files of a Java installation is not
+  an easy task, because the locations vary with your kernel (Linux, SunOS, …)
+  and with your architecture (x86, SPARC, …) and there is no ‘java-config’
+  script we could use. Configuration of the JVM library is therefore a bit
+  tricky.
+
+  The easiest way to use the `--with-java=$JAVA_HOME' option, where
+  `$JAVA_HOME' is usually something like:
+    /usr/lib/jvm/java-1.5.0-sun-1.5.0.14
+
+  The configure script will then use find(1) to look for the following files:
+
+    - jni.h
+    - jni_md.h
+    - libjvm.so
+
+  If found, appropriate CPP-flags and LD-flags are set and the following
+  library checks succeed.
+
+  If this doesn't work for you, you have the possibility to specify CPP-flags,
+  C-flags and LD-flags for the ‘Java’ plugin by hand, using the following three
+  (environment) variables:
+
+    - JAVA_CPPFLAGS
+    - JAVA_CFLAGS
+    - JAVA_LDFLAGS
+
+  For example (shortened for demonstration purposes):
+
+    ./configure JAVA_CPPFLAGS="-I$JAVA_HOME/include -I$JAVA_HOME/include/linux"
+
+  Adding "-ljvm" to the JAVA_LDFLAGS is done automatically, you don't have to
+  do that.
