Installing Jahia

Hello,
I have a devlopper that has devlopped and configured jahia and  
created modules to go with it. He builded his version on a Pc, and I  
am currently running under linux.
he send me his whole : jahia4.1.0_01_b6070 directory containing:  
bin/  jahia.bat*  License.txt*  shutdown.bat*  tomcat/  Uninstall.exe*
My question is how do I install his code.

My server conffiguration is usually, I put my webapps under:  /usr/ 
local/jakarta/jakarta-tomcat-5.5.7/webapps/

How do I edit the configs to work under linux?

Thanks,
Charles
