Re: [Duplicity-talk] problems trying to use par2

[edgar . soldin]

right,

http://duplicity.nongnu.org/duplicity.1.html#sect30
lists the command line binary 'par2cmdline' but not pexpect, probably because 
it is usually a dependency by the distro's packaging as it is needed for 
pexpect+ssh://, the legacy ssh backend.

how about providing a patch for the manpage ;) adding the pexpect line. it is 
already there for pexpect ssh?
