In fact, this is sort of what libvirt does. We have a 'run.in' script template at the top directory, then create 'run' in the build tree (whether or not it is a VPATH tree); the run script then primes any necessary environment variables to execute commands using the build tree as its preferred location for executables, dynamic libraries, and helper files. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
