Build dependencies
------------------
- bitlbee and headers >= 3.4
  If using distribution version of bitlbee you will need to install the dev
  package, usually bitlbee-dev or bitlbee-devel. If bitlbee was built from
  source don't forget to do `make install-dev`.

- libwebsockets >= 1.6 and headers (https://libwebsockets.org)
  Archlinux users can use libwebsocket-git from AUR, others are out of luck and
  will have to build it from source for now, debian's version in sid is too old
  (1.2), fedora23 doesn't provide this package at all.

- glib2 and headers => 2.32
  The library itself is usually installed as a dependency of bitlbee, headers
  need to be installed separately. In debian the package containing them is
  libglib2.0-dev.

- autotools (if building from git)
  A bit of an overkill, but autotools is a buildsystem of choice now, sorry.


Building and Installing
-----------------------
If building from git you will first need to generate autotools configuration
script and related files by executing the following command:

  $ ./autogen.sh

After that (or when building from a tarball) you can build as usual:

  $ ./configure
  $ make
  $ sudo make install

If your bitlbee's plugindir is in non-standard location you can specify it by
calling ./configure with --with-plugindir=/path/to/plugindir option.

Usage
-----
Plugin adds 'discord' protocol to bitlbee, add your account as usual:

  > account add discord <email> <password>
  > account discord on

Options
-------
This section describes options available throug "account set" bitlbee command
(for help on usage of this command see "help account set").

  - host (type: string; default: "discordapp.com")
    Discord server hostname. Just in case discord changes the hostname or there
    are some alternatives with compatible API.

  - voice_status_notify (type: boolean; default: no)
    This enables text notifications in your control channel about users
    changing/leaving voice channels. Can be noisy on big servers.

  - edit_prefix (type: string; default: "EDIT: ")
    A string that will be prefixed to an edited message to distinguish those
    from normal ones.

  - urlinfo_handle (type: string; default: "urlinfo")
    User handle that will be used to post url expansion info such as title and
    description in groupchats.

  - max_backlog (type: integer; default: 50)
    Maximum number of backlog messages per channel to fetch on connection.
    Unlike twitter implementation in bitlbee this won't dump seen messages.

  - send_acks (type: boolean; default: yes)
    By default bitlbee-discord will send an "ack" for every message received,
    thus marking everything as "read" on mobile/webapp. Setting this to false
    will disable all acks from bitlbee-discord.

  - mention_suffix (type: string; default: ":")
    Suffinx used in a regex to look for username mentions to automatically
    convert your usual irc-style "nick:" mentions to discord's "<@id>" format.
    So if you type "nick: hello" in bitlbee, it will be displayed as
    "@nick hello" in discord. This can be multicharacter and you can even do OR
    logic here because it is actually used as a part of glib regex. That is
    setting this to "[:,]" will match both "nick:" and "nick,". But beware
    overcomplicating this may lead to bitlbee-discord spending a lot of time
    parsing your outgoing messages. Setting this to "" will disable this
    function.

  - mention_ignorecase (type: boolean; default: off)
    Ignore case when looking for outgoing mentions. This also affects channel
    mentions.

  - incoming_me_translation (type: boolean; default: on)
    This option controls wheter bitlbee-discord will translate incoming
    messages that are fully italized(that is enclosed in '*' characters) to
    '/me' messages.

  - never_offline (type: boolean; default: off)
    Contacts from this account will never appear as offline and will be marked
    away instead.
