Situation is I have to configure an application in one of two ways, and it is determined by the first character of a users first name.

What I would like to do is create a single bundle with the core application install action, then have a couple of additional actions with individual requirements on each to determine which setup a users gets. Since the deciding factor is the users first name, I can look at either the NWUSERNAME environment variable or a user Registry key (haven't figured out which on to reference right now).

To make this work, I would like to use a fairly simple regular expression to check the first character of the NWUSERNAME environment variable

I thought this was something that could be done, but unable to get it to work right now. Are real expressions even supported in ZCM?
