• Special programming features :

  Shell script user interface using SuperCode. Plans exist to replace SuperCode by a Python user interface.

  
  

• Comments :

  Documentation of ORBIT is out of date, but the authors are accessible and glad to help.
  
  See also this ORBIT page http://www.sns.gov/APGroup/Codes/orbit.htm with a standard (old) compressed tar file with the source code.
