Comment (by dcf):

 I tried it today. I don't know Docker very well, but it looks good, this
 is solid work.

 I [https://gitweb.torproject.org/pluggable-
 transports/snowflake.git/commit/?id=88f282c7334f9ee76dccbf9b84dc7bcf0b39cd5b
 added a link] from the main README. I'm not opposed to moving this into
 the main snowflake tree if you think that's a better place for it.

 It's possible to override torrc settings on the command line. An
 alternative to writing separate torrc-$count files is this:
 {{{#!diff
 -    cp torrc-localhost torrc-$count
 -    sed -i -e "s/datadir/datadir$count/g" torrc-$count
 -    echo "SOCKSPort $(($count+9050))" >> torrc-$count
 +    config_override=""
 +    config_override="$config_override DataDirectory datadir$count"
 +    config_override="$config_override SOCKSPort $(($count+9050))"

 -    nohup tor -f torrc-$count > client-$count.log 2> client-$count.err &
 +    nohup tor -f torrc-localhost $config_override > client-$count.log 2>
 client-$count.err &
 }}}
 I was going to file a pull request for this, but then I thought, it could
 be nice to have a torrc file to examine. So I'll just leave the idea here.
