#
# 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 - Casper Pedersen <casper [at] fedoranews.org>
#                Fixed an issue with "kill -9 $kipd" in line 135 to "kill -9 $kpid"
#                Thanks goes to Marc Gimpel for pointing it out.
