3. setenv.sh(download zip version)

CATALINA.SH said

Do not set the variables in this script. Instead put them into a script

#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

Where do we config that stuff?

- Global(all tomcat) option: config by using path 

- Specific(a tomcat) option: config by using script

3_1. To make a setenv.sh

- CATALINA.SH call a setenv.sh

3_2. If we config a
