[izpack-devel] mutually exclusive packs

[vralev at redhat.com]

Hello everyone.

I was working on this feature these days and want to hear your comments on the
syntax. I addes a new tag <excludes> similar to <depends>:

<pack name="1" installGroups="1" required="no">
    <depends packname="somedeppack"/>
    <excludes packname="2"/>
</pack>
<pack name="2" installGroups="1" required="no">
    <excludes packname="1"/>
</pack>

Packs declared in <excludes> are being unchecked when the parent pack is
checked. There is a compiler-time check similar to the depends' and a runtime
check to ensure a requred pack isn't being unchecked.
