/**
* OK - here's where we store the definitions.
*
* Good place for information about BT peer ID conventions:
* http://wiki.theory.org/BitTorrentSpecification
* http://transmission.m0k.org/trac/browser/trunk/libtransmission/clients.c (hello Transmission authors!) :)
* http://rufus.cvs.sourceforge.net/rufus/Rufus/g3peerid.py?view=log (for older clients)
* http://shareaza.svn.sourceforge.net/viewvc/shareaza/trunk/shareaza/BTClient.cpp?view=markup
* http://libtorrent.rakshasa.no/browser/trunk/libtorrent/src/torrent/peer/client_list.cc
*
* By default - if you are unsure about a client's versioning scheme, you should
* register it without passing an explicit value.
*
* There are some clients which generate peer ID's in Azureus style, but some don't
* provide accurate or maybe even any information about what version they are.
*
* I've decided that we should follow this criteria - if a client generates a peer
* ID which strictly matches the Az-style specification (0'th char is '-', 7'th char
* is '-'), then we should include it in this list - if there's no derivable version
* information, then we flag it as NO_VERSION.
*
* Oh, and hello any closed source BitTorrent client authors who may be reading! ;)
