How to install Routlets
-----------------------

1. Ensure a recent Java SE installation is available:
   - this can be downloaded from http://java.com
   - the minimum supported version is 1.6.0_12 
     (otherwise any version like 1.6.0_x, 1.7.0_x or 1.8.0_x is fine)
   - please confirm this is installed correctly by opening a command prompt window and running:
         java -version
   - (this step can generally be ignored for Mac OS X, which will self-configure Java)

2. Unzip the appropriate downloaded Routlets zip file to any chosen directory

3. Launch the routlets executable in the Routlets subdirectory
   - e.g. Routlets/routlets.exe in Windows
   - e.g. Routlets/routlets in OS X and Linux

Troubleshooting
---------------

"Failed to load the JNI shared library ... jre\bin\server\jvm.dll"
   If a message such as this appears while trying to launch Routlets, please check
      if the 32 or 64 bit version of Routlets has been downloaded.
   The following command will confirm if the Java SE installation is 64 bit
         java -version
      (look for a message like "Java HotSpot(TM) 64-Bit..." for a 64 bit installation
      or no mention of "64-Bit" for a 32 bit installation)
