[Php-java-bridge-users] standalone JVM bridge init script

[<php...@li...>]

Here is a little init script I wrote that I use to start/stop a php- 
java-bridge standalone instance on my machine.

It took quite a bit of messing around to get all the various pieces  
working and robust (ie logging startup failure output to the log file;  
properly detecting the PID of java, etc).

I am not 100% confident that the line that launches the bridge is  
perfect; so use your own knowledge to correct it. I am talking to Jost  
in another thread about it at this time.
