Zimbra application components

[Vimm]

I need to make a list of every application that Zimbra is running in a full installation. Does such a list exist somewhere? By viewing the directory structure of /opt/zimbra I've come up with the following:

amavisd 2.4.3
clamav 0.88.7
cyrus-sasl 2.1.21
dspam 3.6.2
httpd 2.0.54
java 1.5.0_08
myql 5.0.33
openldap 2.3.21
perdition 1.17
postfix 2.2.9
sleepycat 4.2.52.4
snmp 5.4
tomcat 5.5.15

I know that list is missing a few things (such as PHP). Can someone help me fill in the gaps or point me to a place where this is documented? Thanks.

This list should give an idea of what's in there.

Thanks, that's what I was looking for. Odly though, I don't see PHP listed. It's definitely being used for the Spell Checker (/opt/zimbra/httpd/htdocs/aspell.php) so shouldn't it be listed too, or is it being considered a part of something else?
