Config files
------------

INI-like, syntax is the following : <key> = <value>.
Comments are "#", not ";" as you may expect. See [boost ticket](https://svn.boost.org/trac/boost/ticket/808)
All command-line parameters are allowed as keys, for example:

i2p.conf:

    log = 1
    v6 = 0

tunnels.cfg (filename of this config is subject of change):

    # outgoing tunnel sample, to remote service
    # mandatory parameters:
    # * type -- always "client"
    # * port -- local port to listen to
    # * destination -- i2p hostname
    # optional parameters (may be omitted)
    # * keys -- our identity, if unset, will be generated on every startup,
    #     if set and file missing, keys will be generated and placed to this file
    # * address -- local interface to bind
    # * signaturetype -- signature type for new destination. 0,1 or 7
    [IRC]
    type = client
    address = 127.0.0.1
    port = 6668
    destination = irc.postman.i2p
    keys = irc-keys.dat
    #
    # incoming tunnel sample, for local service
    # mandatory parameters:
    # * type -- always "server"
    # * host -- ip address of our service
    # * port -- port of our service
    # * keys -- file with LeaseSet of address in i2p
    # optional parameters (may be omitted)
    # * inport -- optional, i2p service port, if unset - the same as 'port'
    # * accesslist -- comma-separated list of i2p addresses, allowed to connect
    #    every address is b32 without '.b32.i2p' part
    [LOCALSITE]
    type = server
    host = 127.0.0.1
    port = 80
    keys = site-keys.dat
    inport = 81
    accesslist = <b32>[,<b32>]
