Two new questions

[EJ Ciramella]

1 - Is there any way to make a profile stored in profiles.xml the
default active profile?  I don't see a way to do that unless the profile
I want is in the pom.xml (I don't want to do this).
 
2 - Is there a way from a top level directory to say "compile module-A
only", or do I have to change directories to module-A and do a mvn
compile each time?
