[lug] Automake question: Checking for subdirs?

[Scott A. Herod]

Hello,

  Another automake question if you don't mind.  With automake
you can add SUBDIRS and the resulting Makefiles will recursively
enter these directories.  However, the scripts don't check to see
if the subdirectories actually exist.  I'd like to wrap a test around
the scripts in the Makefile that verifies the subdirectory exist 
before descending into it.  Will I have to change the configuration
defined in /usr/share/automake/ to do that?

Thanks,

Scott
