[svlug] Shell scripting is biting me! :)

my point was not the {} stuff but the  "" stuff...
if your dirpath=/bla/bla bla (notice the space?)
then `dirname` will get you: bla bla
sosetting PROJ_ROOT=bla bla 
will give you an error message bla not found
however...
PROJ_ROOT="bla bla"
will work correctly
