What is the status of these par2 patches? It's been almost 2 years since
the last comment; has the functionality been incorporated into
duplicity? (I've been generating the PAR2 files for my duplicity backups
manually and it's fairly annoying.)

Title:
  [PATCH] par2 creating support

Status in Duplicity - Bandwidth Efficient Encrypted Backup:
  In Progress

Bug description:
  OK, this add support for creating par2 recovery files for every file
  that gets uploaded to the backend.

  - can be enabled by passing --par2. If the backend already contains par2 files there is no need to pass the --par2 option.
  - the par2 files are created just before the upload of the file so this will not break the asynchronous mode.
  - all par2 files are preserved in the local cache and uploaded to the backend.

  
  todo:
  - add comments and logging
  - add support for customizing the pa2 options currently 20% redundancy is used which might be an overkill or too little for someone
  - don't use os.system and add error handling.
  - add support for recovery.
    
  Code review will be greatly appreciated. There are some very ugly hacks with temp files
