[wpkg-users] newbie questions

In many packages I see this line: check type="uninstall" 
condition="exists" path="filezilla" />

The way I understand this is: Do not install, if software already exists 
on the machine. What I don't understand is on the "path" variable is 
only the software name. How does it know where to look?

What about the exit codes? Are the "exit codes" I've seen in the 
packages syntax for the purpose of
displaying error messages if the install fails?

Thank you
