# 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 - Fix pidfile and config tags
# version 1.10 - Fallback to su direct use on systems without Redhat/Mandrake init.d functions
# version 1.11 - Fix webapps dir permissions
# version 1.12 - remove initial start/stop level for chkconfig (- 80 20)
# version 1.13 - remove chown of logs/work/temp/webapps dir, owned by tomcat4 at install time
# version 1.14 - correct the start/stop ugly hack by waiting all the threads stops
# version 1.15 - ensure we're looking for TOMCAT_USER running catalina
# version 1.16 - Add support for CATALINA_PID env var
# version 1.17 - Remove run files only tomcat started correctl
#                in start area, check that tomcat is not allready running
# version 1.18 - Fix kill typo (thanks Kaj J. Niemi)
# version 1.19 - Add jar relinking
# version 1.20 - Check there is no stalling tomcat4.pid
# version 1.20tc5 - Changed all instances of tomcat4 to tomcat5 except TOMCAT_USER
#
