Hi Mariano,

If you haven't already read chapter 6 of the Sys Admin guide, you should
definitely start there. In particular, pay attention to the "Published" and
"Publisher" information. That may be a good example/template for what you
are trying to do.

One idea that might work, is to define a Symbol Dictionary for each version
of your application. For example, MyAppV11Globals versus MyAppV12Globals
versus MyAppV21Globals, etc.

For each application user, insert the appropriate version Symbol Dictionary
into his (or her) Symbol List. You probably want some scripts to help
facilitate this, since you may have more than one user. Unfortunate, I don't
see anything that facilitates managing the Symbol List from a group

Does that help?
