[libtorrent] Is there a way to see all available options for b2 and how to build the docs

[sledgehammer999]

I am starting to play with 1.1.x. I see that some options for b2 were
renamed or removed.
Is there a way to make it spew all available switches?

What is the equivalent of the old "boost=source" switch?
geoip is gone completely, right?
If I have "crypto=openssl" do I need to also set "encryption=on"?
I see in the Jamfile a `windows-version` switch. Do I need to use it?
There are some other switches not documented in building.html...

Also how do you build the docs from source?
I have launched the index.html file, but there isn't a reference.html
file...

I'm not aware of a way to make bjam do that from the command line. There
are tons of built-in features and features defined by boost though, so all
of them might not be all that useful.
The ones defined by libtorrent can be listed by just grepping for "feature"
in the root Jamfile.

If the environment variable BOOST_ROOT is defined, libtorrent will build
and link against boost from source, otherwise it will expect to find shared
libraries in the default library path.

yes.

encryption=on is on by default, and refers to the bittorrent protocol
encryption, which does not require openssl. If you want SSL support (for
both bittorrent and HTTPS) you need to say crypto=openssl.

That's a way to control the version of the windows SDK to build against
(i.e. _WIN32_WINNT). If you want to support XP, you should say
windows-version=xp

There may be a few I've added for debugging specific issues. I believe all
the relevant ones are documented though.

There's a makefile in the docs directory. You need docutils' rst2html and
dot and aafigure for figures and python for generating documentation.
