[Zhang, Cynthia X. (GSFC-710.0)[BOOZ ALLEN HAMILTON]]

Hello, my name is Cynthia Zhang and I am a Supply Chain Risk Management Analyst 
at NASA. NASA is currently conducting a supply chain assessment of Kdenlive.
We are interested in confirming the following information:

  1.  Is there an organization which sponsors/publishes the project, or a 
primary developer who audits the code for potential vulnerabilities, errors, or 
malicious code? Y/N
  2.  Please list the country or list of countries where most contributions 
originate from.
Thank you,
Cynthia Zhang
