+# BIRD upstream packaging sources
+
+This distro/ directory contains packaging sources initially copied from Debian
+and Fedora downstream repos.
+
+Files in this directory follow [apkg] conventions and apkg can be used to
+create BIRD packages for various distros directly from upstream sources as
+well as from upstream archives.
+
+[apkg]: https://apkg.rtfd.io
+
+
+## Create (source) package from current repo commit
+
+Following command should build source package for current distro directly
+from current repo state - run at top bird directory:
+
+    apkg srcpkg
+
+or build native packages directly:
+
+    apkg build
+
+or in case of disposable VM/container you can use faster direct host build
+
+    apkg build -Hi
+
+tools/make-dev-archive script is in charge of creating archive from source.
+
+
+## Create (source) package from upstream release
+
+Following commands can be used to clone upstream repo, download current upstream
+archive (tarball), and build Debian, Ubuntu, Fedora, CentOS, or OpenSUSE
+source package (depending on host system) using files in bird/distro:
+
+    git clone https://gitlab.nic.cz/labs/bird
+    cd bird
+    apkg get-archive
+    apkg srcpkg -a pkg/archives/upstream/bird-2.0.8.tar.gz
+
+To create native packages instead use `build`:
+
+    apkg build -a pkg/archives/upstream/bird-2.0.8.tar.gz
+
+Or to build packages directly in case of a disposable VM/container (faster, modifies system):
+
+    apkg build -Hi -a pkg/archives/upstream/bird-2.0.8.tar.gz
+
+
+## Build packages in openSUSE Build Service (OBS)
+
+tools/make-obs script can be used on Debian-based system to create OBS
+source package in pkg/obs directory ready to be uploaded:
+
+    cd bird
+    apkg get-archive
+    ./tools/make-obs
+    # result in pkg/obs
+
+You can also supply (upstream) archive to build from:
+
+    # or to use specified archive
+    ./tools/make-obs pkg/archives/upstream/bird-2.0.8.tar.gz
+
+
+## More Info
+
+Please see [apkg docs][apkg].

+
+A manual page <package>.<section> will be generated. You may view the
+manual page with: nroff -man <package>.<section> | less'. A typical entry
+in a Makefile or Makefile.am is:
+
+DB2MAN = /usr/share/sgml/docbook/stylesheet/xsl/nwalsh/manpages/docbook.xsl
+XP     = xsltproc -''-nonet -''-param man.charmap.use.subset "0"
+
+manpage.1: manpage.xml
+        $(XP) $(DB2MAN) $<
+
+The xsltproc binary is found in the xsltproc package. The XSL files are in
+docbook-xsl. A description of the parameters you can use can be found in the
+docbook-xsl-doc-* packages. Please remember that if you create the nroff
+version in one of the debian/rules file targets (such as build), you will need
+to include xsltproc and docbook-xsl in your Build-Depends control field.
+Alternatively use the xmlto command/package. That will also automatically
+pull in xsltproc and docbook-xsl.
+
+Notes for using docbook2x: docbook2x-man does not automatically create the
+AUTHOR(S) and COPYRIGHT sections. In this case, please add them manually as
+<refsect1> ... </refsect1>.
+
+To disable the automatic creation of the AUTHOR(S) and COPYRIGHT sections
+read /usr/share/doc/docbook-xsl/doc/manpages/authors.html. This file can be
+found in the docbook-xsl-doc-html package.
+
+Validation can be done using: `xmllint -''-noout -''-valid manpage.xml`

+    <para><command>bird</command> is an Internet Routing Daemon. That is,
+      it sends and receives messages using different protocols in order to
+      discover and exchange routing information with other routing daemons
+      present on the same network. It is able to talk the most widely
+      known routing protocols (such as BGPv4, RIPv2, OSPFv2 and OSPFv3),
+      both on IPv4 and IPv6 and it features a very powerful language for

+      status and reconfigure it. The two processes use a Unix socket to
