#Notes about JPype
#------------------------------------
#You need to install default-jre / openjdk-6-jre (Debian/Ubuntu), or 
#java-1.6.0-openjdk (RHEL/CentOS) *and* associated development packages.
#The JAVA_HOME variable should be
#set as an environmental variable prior to using the following.
#You might want to use the following to set this:
#Ubuntu: export JAVA_HOME="/usr/lib/jvm/java-6-openjdk"
#RHEL:   export JAVA_HOME="/etc/alternatives/java_sdk"
#and include these in your profile (eg ~/.bash_profile) to load them on
#startup.
