New Revision: 27126
URL: http://svn.gna.org/viewcvs/relax?rev=27126&view=rev
Log:
Created the Structure.test_atomic_fluctuations_gnuplot system test.
This checks the operation of the structure.atomic_fluctuations user function
when the output format
is set to 'gnuplot'. This will be used to implement this option. The current
gnuplot script
expected by this test is just a very basic starting script for now.
