sure whatever, as I said I don't have a problem with working around it.

which globbing code ? Patches welcome as always.

No that is not correct. You can use the following inside a build file:
<property name="nant.settings.currentframework" value="net-1.0" />
<!-- do some compilation against 1.0 -->
<property name="nant.settings.currentframework" value="net-1.1" />
<!-- do some compilation against 1.1 -->
you can also use the -k:net-1.0 commandline option to specify a default
framework for that build run. You only need to set it in the config file
once to somthing reasonable for your installation. This is analagous to
Ant using the JAVA_HOME environment variable to find a jdk.
If you don't ever need to target multiple frameworks then its a
non-issue - just make sure the default is correct at install time and
you'll never have to worry about it again. However if you do need the
ability - its there.

So basically "don't use regex's" right ?
