[tor-commits] [stem/master] Module for Tor manual information
commit 53accd666eeceae94ab3ee7f54236c624fcfe174
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>
Date: Sat Nov 21 11:41:32 2015 -0800
Module for Tor manual information
Nyx, Erebus, and Stem's interpreter all have use for human readable information
about tor's configuration options. Nyx has long parsed the man page for this
but like most of Nyx it was pretty cobbled together. No tests, poor
performance, and not very general purpose.
https://trac.torproject.org/projects/tor/ticket/8251
Moving the useful bits of Nyx over and expanding it to be an order of magnitude
faster (by calling 'man -P cat' to avoid its pager) and have a great compliment
of tests.
Note that the tests presently expect the tor man page in our test directory but
it doesn't exist. I'll be addressing this in an upcoming commit, but I don't
want to add the man page to our git history (no need to artificially inflait
our repository size).

+Tor is a connection-oriented anonymizing communication service. Users choose a source-routed path through a set of nodes, and negotiate a "virtual circuit" through the network, in which each node knows its predecessor and successor, but no others. Traffic flowing down the circuit is unwrapped by a symmetric key at each node, which reveals the downstream node.
+
+Basically, Tor provides a distributed network of servers or relays ("onion routers"). Users bounce their TCP streams - web traffic, ftp, ssh, etc. - around the network, and recipients, observers, and even the relays themselves have difficulty tracking the source of the stream.
+
+By default, tor will only act as a client only. To help the network by providing bandwidth as a relay, change the ORPort configuration option - see below. Please also consult the documentation on the Tor Project's website.

(Default: 1 GByte)\n\nWith this option, and in other options that take arguments in bytes, KBytes, and so on, other formats are also supported. Notably, "KBytes" can also be written as "kilobytes" or "kb"; "MBytes" can be written as "megabytes" or "MB"; "kbits" can be written as "kilobits"; and so forth. Tor also accepts "byte" and "bit" in the singular. The prefixes "tera" and "T" are also recognized. If no units are given, we default to bytes. To avoid confusion, we recommend writing "bytes" or "bits" explicitly, since it\'s easy to forget that "B" means bytes, not bits.'
