ansible/roles/bird/README.md

-Role Name
-=========
-
-A brief description of the role goes here.
-
-Requirements
-------------
-
-Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
-
-Role Variables
---------------
-
-A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
-
-Dependencies
-------------
-
-A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
-
-Example Playbook
-----------------
-
-Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
-
-    - hosts: servers
-      roles:
-         - { role: username.rolename, x: 42 }
-
-License
--------
-
-BSD
-
-Author Information
-------------------
-
-An optional section for the role authors to include contact information, or a website (HTML is not allowed).

ansible/roles/bird/files/bird-2.0.7/INSTALL

-How to install BIRD
-===================
-
-$ ./configure
-$ make
-# make install
-
-Default location for configuration file is /usr/local/etc/bird.conf and
-for control socket is /usr/local/var/run/bird.ctl . You can change that
-by --prefix, --sysconfdir and --runstatedir configure options, e.g.:
-
-$ ./configure --prefix=/usr --sysconfdir=/etc --runstatedir=/run
-
-To compile current development BIRD source code from Git repository, you
-also need Git (to download the source code) and Autoconf (to generate
-the configure script and associated files using 'autoreconf' tool):
-
-$ git clone https://gitlab.labs.nic.cz/labs/bird/
-$ cd bird
-$ autoreconf
-
-Then continue as in usual installation above.
-
-
-Requirements
-============
-
-For compiling BIRD you need these programs and libraries:
-
- - GNU C Compiler (or LLVM Clang)
- - GNU Make
- - GNU Bison
- - GNU M4
- - Flex
-
- - ncurses library
- - GNU Readline library
- - libssh library (optional, for RPKI-Router protocol)
-
-For compiling BIRD documentation you also need:
-
- - Linuxdoc-Tools
- - LaTeX

-
-================================================================================
-
-The BIRD project aims to develop a dynamic IP routing daemon with full support
-of all modern routing protocols, easy to use configuration interface and
-powerful route filtering language, primarily targeted on (but not limited to)
-Linux and other UNIX-like systems and distributed under the GNU General
-Public License.
-
-What do we support
-==================
-
-	o  Both IPv4 and IPv6
-	o  Multiple routing tables
-	o  Border Gateway Protocol (BGPv4)
-	o  Routing Information Protocol (RIPv2, RIPng)
-	o  Open Shortest Path First protocol (OSPFv2, OSPFv3)
-	o  Babel Routing Protocol (Babel)
-	o  Bidirectional Forwarding Detection (BFD)
-	o  IPv6 router advertisements
-	o  Static routes
-	o  Inter-table protocol
-	o  Command-line interface allowing on-line control and inspection of
-	   status of the daemon
-	o  Soft reconfiguration, no need to use complex online commands to
-	   change the configuration, just edit the configuration file and notify
-	   BIRD to re-read it and it will smoothly switch itself to the new
-	   configuration, not disturbing routing protocols unless they are
-	   affected by the configuration changes
-	o  Powerful language for route filtering, see doc/bird.conf.example
-	o  Linux, FreeBSD, NetBSD and OpenBSD ports
-
-How to install BIRD
-===================
-
-	o  From standard distribution package of your OS (recommended)
-	o  From official binary packages for Debian and Red Hat Linux
-	   ftp://bird.network.cz/pub/bird/debian/
-	   ftp://bird.network.cz/pub/bird/redhat/
-	o  From source code of the latest stable release version
-	   ftp://bird.network.cz/pub/bird/
-	o  From current development code in Git repository
-	   https://gitlab.labs.nic.cz/labs/bird/
-
-See the file INSTALL for information about installation from source code.
-
-Documentation
-=============
-
-Online documentation is available at http://bird.network.cz/?get_doc or as HTML
-files in the doc directory, you can install it by `make install-docs' and
-rebuild it by `make docs', but you'll need SGMLtools and LaTeX to be installed
-on your machine. You can also download a neatly formatted PDF version as
-a separate archive (bird-doc-*.tar.gz) from ftp://bird.network.cz/pub/bird/
-
-User support
-============
-
-If you want to help us debugging, enhancing and porting BIRD or just lurk
-around to see what's going to develop, feel free to subscribe to the BIRD
-users mailing list bird-users@network.cz, just send `subscribe' to
-bird-request@network.cz. Bug reports, suggestions, feature requests and
-code are welcome! We don't use gitlab issues for reporting, sorry.

-History
-=======
-
-BIRD development started as a student project at the Faculty of Math
-and Physics, Charles University, Prague, Czech Republic under supervision
-of RNDr. Libor Forst <forst@cuni.cz>. BIRD has been developed and supported
-by CZ.NIC z.s.p.o. http://www.nic.cz/ since 2009.

-
-Good Luck and enjoy the BIRD :)
