+Debian packaging for libyang
+============================
+
+Where to file issues
+--------------------
+
+Please file issues on the Debian BTS as usual.  You could also open issues
+on github, but if it's something about the Debian packaging it's better to
+stick with the proper Debian ways.  The Debian BTS is where other people
+involved with Debian go look for bugs regarding a package, so that's where
+they should be.
+
+Building straight off git
+-------------------------
+
+Just the normal:
+
+```
+git clone https://github.com/CESNET/libyang -b debian/master
+cd libyang
+dpkg-buildpackage
+```
+
+Building a Debian .dsc
+----------------------
+
+Again, pretty much the normal:
+
+```
+git clone https://github.com/CESNET/libyang -b debian/master
+wget -Olibyang_0.16.105.orig.tar.gz https://github.com/CESNET/libyang/archive/v0.16-r3.tar.gz
+cd libyang
+dpkg-source -b .
+```
+
+(Note the diverging release numbering though.)

+This module uses gbp and upstream git repository
+
+To update this package, first import the changes from upstream:
+- git fetch --all
+
+Find the latest version:
+VERSION=$(git describe --tags $(git rev-list '--tags=v2*' --max-count=1) | sed 's/^v//')
+echo $VERSION
+
+Update debian/sid branch
+- git checkout debian/master
+- git merge v$VERSION
+
+Update the debian/copyright file:
+- cme update dpkg-copyright
+See also https://github.com/dod38fr/config-model/wiki/Updating-debian-copyright-file-with-cme
+
+Check patches (and cleanup if necessary):
+- gbp pq rebase --commit --drop
+
+Download upstream tarball:
+- uscan --download --verbose --download-version $VERSION
+
+Add pristine-tar:
+- pristine-tar commit ../libyang_$VERSION.orig.tar.gz v$VERSION
+
+Generate a temporary changelog:
+- gbp dch --new-version=$VERSION-1 --snapshot --auto --commit debian/
+
+Test the first build::
+- gbp buildpackage --git-ignore-new --git-pristine-tar --git-no-purge
+
+Regenerate the symbol file (See https://qt-kde-team.pages.debian.net/symbolfiles.html)
+- pkgkde-symbolshelper batchpatch -v $VERSION < <path_to>/buildlog
+
+See https://www.debian.org/doc/manuals/maint-guide/advanced.en.html#librarysymbols
+and dpkg-gensymbols man page
+
+Update the changelog:
+- gbp dch -Ra -c
+
+Once everything is fine, build a source package and tag:
+- gbp buildpackage -S --git-tag
+
+Push on salsa:
+- gbp push
+
+For more details, see

+
+Maintainer Notes (moved from README.md)
+=======================================
+
+* the project version number is actually the SO ABI version.  The release
+  point numbers (0.16-r3) isn't used for Debian.
+
+* it's intentional that the SONAME is libyang.so.0.16 and not libyang.so.0.
+  ABI compatibility is indicated by the first two numbers being equal;
+  the third number is incremented for compatible changes.  cf.
+  CESNET/libyang#656
+
+* the watch file doesn't work yet but the libyang people agreed to make
+  future release tags the same as the internal version number.  At that point
+  the watch file will work.

+Description: parser toolkit for IETF YANG data modeling - runtime
+ Libyang implements functions to process schemas expressed in the
+ YANG data modeling language defined by the IETF in RFCs 6020/7950.
+ Schemas expressed in this language primarily describe configuration
+ used by larger network equipment like routers and switches.
+ .
+ In addition to handling the schemas itself, the library also provides
+ functions to process data described by the schemas.
+ .
+ The library is implemented in C and provides an API for other software
+ to use in processing configurations.

+Description: parser toolkit for IETF YANG data modeling - executable tools
+ This package provides the "yanglint" and "yangre" tools which can be used

+Description: parser toolkit for IETF YANG data modeling - YANG modules
+ This package provides the IETF YANG modules used by libyang. These modules
