[Wien] passing env variables to lapw1 and 2

[Peter Blaha]

I'm not sure, why you would not set this permanently in .bashrc.

Anyway, if ssh does not allow it on your system, you could modify your 
lapw1/2para_lapw script and "source" a file in your directory which 
contains the desired settings.

The lines to modify are:

		  ($remote $machine[$p] "cd $PWD;$t $taskset0 $exe ${def}_$loop.def 
;fixerror_lapw ${def}_$loop";rm -f .lock_$lockfile[$p]) >& 
.stdout1_$loop; sortoutput 1_$loop &


where you could put some sourcing between cd $PWD;source ...;$t ...

(must be csh commands, not bash).
