Since gathering some statistics is slow (network connections, slow devices,

used and should be found in various implementations for hopefully all
platforms.

-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, LD-flags and LIBS for the ‘Java’ plugin by hand, using the
- following environment variables:
-
- - JAVA_CPPFLAGS
- - JAVA_CFLAGS
- - JAVA_LDFLAGS
- - JAVA_LIBS
-
- For example (shortened for demonstration purposes):
-
- ./configure JAVA_CPPFLAGS="-I$JAVA_HOME/include -I$JAVA_HOME/include/linux"
-
- Adding "-ljvm" to JAVA_LIBS is done automatically, you don't have to
- do that.
-
Generating the configure script
-------------------------------
The `build.sh' script takes no arguments.
