-------------------------+-------------------------------------
 The current exit scanner is purpose written software using Haskell. It is
 non-trivial to update this program to run on a modern Debian system and
 would be easier in the longer term to simply replace.

 This task requires the new exit list specification to be completed in
 #29624.

 Expected new features:

 * Written in Python
 * Support for IPv6
 * Support for new exit list format

 Features we would like:

 * Cryptographically signed measurement results
 * Archival signatures
