Hi,

  My name is Sreenatha Bhatlapenumarthi. I'd like to migrate TorBEL 
  from TorCtl to Stem as a part of GSoC'13 project this summer.

  Damian pointed out that there is still some improvement to be made to
  TorBEL to replace DNSEL. I've downloaded the source code from [0] and 
  started looking around for missing functionality and components that use 
  TorCtl(and hence need migration) and here is what I've observed:
 Please let me know if I've missed something or got something wrong.

 I donot have any background on Haskell as such but if you recommend that I
 learn it inorder to understand TorDNSEL, I am prepared to spend the required
 amount of time learning it during May before the coding period starts. Also, can 
 you give me a rough estimate of how long you think the migration will take so that 
 I can plan the project timeline accordingly?
 
 Thanks for taking your time out to read this.
