Exciting! - a developer-friendly DFT package. 
<br>
<br>

Take a look under the hood of your favorite code package. 
Is there anything you would like to improve? Many 
PhD students around the world are using code they inherited 
from their fellow students or supervisors. Not everyone 
can interpret what’s going on deep down in the ancient 
FORTRAN 66 subroutines written by someone who is now 
a well respected professor, but back then was a dope 
smoking hippie with lots of other things on his mind than 
documenting and commenting his computer code.

The electronic structure code EXCITING! was written in two 
years, mainly by one postdoc in Graz, Austria. His 
task was to implement some simple things in another 
density functional theory code that was so poorly written that 
the postdoc decided to write his own program. 
And this time in a way which would simplify the life of others who 
wishes o make a contribution to the development of electronic structure methods.
