# version 1.02 - Removed initlog support
# version 1.03 - Removed config:
# version 1.04 - tomcat will start before httpd and stop after httpd
# version 1.05 - jdk hardcoded to link /usr/java/jdk and tomcat runs as "nobody"
# version 1.06 - split up into script and config file
# version 1.07 - Rework from Nicolas ideas 
# version 1.08 - Fix work dir permission at start time, switch to use tomcat4
# version 1.09 - Fixed finding functions for init, changed to delete $TOMCAT_HOME/work
#                 on startup
