dh_python3 -p PACKAGE [-V [X.Y][-][A.B]] DIR [-X REGEXPR]

          o if  necessary,  describe   supported   Python   3   versions   via
            X-Python3-Version field in debian/control,

          o build depends on dh-python

          o build-depend on python3 or python3-all or python3-all-dev,

          o build module/application using its standard build system, remember
            to build extensions for all supported Python 3 versions (loop over
            py3versions -vr),

          o install  files to the standard locations, add --install-layout=deb
            to setup.py's install command if your package is using distutils,

          o add python3 to dh's --with option, or:

          o include       /usr/share/cdbs/1/class/python-distutils.mk       in
            debian/rules and depend on cdbs (>= 0.4.90), or:

          o call dh_python3 in the binary-* target,

          o add ${python3:Depends} to Depends

       dh_python3 tries to translate Python dependencies from the requires.txt
       file to Debian dependencies. In many  cases,  this  works  without  any
       additional  configuration because dh_python3 comes with a build-in map-
       ping of Python module names to Debian  packages  that  is  periodically
       regenerated  from  the Debian archive. By default, the version informa-
       tion in the Python dependencies is discarded. If you want dh_python3 to
       generate  more  strict dependencies (e.g. to avoid ABI problems), or if
       the automatic mapping does not work correctly  for  your  package,  you
       have to provide dh_python3 with additional rules for the translation of
       Python module to Debian package dependencies.

       For a package python3-foo that depends on a package python3-bar,  there
       are two files that may provide such rules:

       1. If  the python3-foo source package ships with a debian/py3dist-over-
          rides file, this file is used by  dh_python3  during  the  build  of

       2. If     the    python3-bar    source    package    ships    with    a
          debian/python3-bar.pydist file (and uses dh_python3), this file will
          be       included       in      the      binary      package      as
          /usr/share/dh-python/dist/cpython3/python3-bar. During the build  of
          python3-foo, dh_python3 will then find and use the file.

       set of options in this call. If you need to change options (f.e. a list
       of supported Python 3 versions) for a private directory that is checked
       by default,  invoke  dh_python3  with  --skip-private  option  and  add
       another call with a path to this directory and new options.

   debug packages
       In   binary   packages   which  name  ends  with  -dbg,  all  files  in
       /usr/lib/python3/dist-packages/ directory that have extensions  differ-
       ent  than so or h are removed by default.  Use --no-dbg-cleaning option
       to disable this feature.

   pyinstall files
       Files listed in debian/pkg.pyinstall file will be installed  as  public
       modules  (i.e.  into  .../dist-packages/  directory)  for all requested
       Python versions.

       Syntax: path/to/file [VERSION_RANGE] [NAMESPACE]

       debian directory is automatically removed from the  path,  so  you  can
       place  your files in debian/ directory and install them from this loca-
       tion (if you want to install them in "debian" namespace, set  NAMESPACE
       to  debian). If NAMESPACE is set, all listed files will be installed in
       .../dist-packages/NAMESPACE/ directory.


              o foo.py installs  .../dist-packages/foo.py  for  all  supported
                Python versions

              o foo/bar.py 3.3- installs .../dist-packages/foo/bar.py for ver-
                sions >= 3.3

              o foo/bar.py spam installs .../dist-packages/spam/bar.py

              o debian/*.py  spam.egg  3.2  installs  .../python3.2/dist-pack-
                ages/spam/egg/*.py files

   pyremove files
       If you want to remove some public modules (i.e. files in .../dist-pack-
       ages/ directory) installed by build system (from all  supported  Python
       versions  or  only  from  a  subset  of  these  versions),  add them to
       debian/pkg.pyremove file.


              o *.pth removes .pth files from .../dist-packages/

              o bar/baz.py 3.2 removes .../python3.2/dist-packages/bar/baz.py

   overriding supported / default Python versions
       If you want to override system's list of supported Python  versions  or
       the  default  one  (f.e.  to build a package that includes symlinks for
       older version of Python or compile .py files only for given interpreter
       version),   you   can   do   that   via   DEBPYTHON3_SUPPORTED   and/or
              disable guessing dependencies

              do not remove any files from debug packages

       --no-ext-rename do not add magic tags nor multiarch tuples to extension
       file names

              do not rewrite shebangs

              don't check private directories

       -v, --verbose
              turn verbose mode on

       -i, --indep
              act on architecture independent packages

       -a, --arch
              act on architecture dependent packages

       -q, --quiet
              be quiet

       -p PACKAGE, --package=PACKAGE
              act on the package named PACKAGE

       -N NO_PACKAGE, --no-package=NO_PACKAGE
              do not act on the specified package

       -V VRANGE
              specify list of supported Python 3 versions.  See  py3compile(1)
              for examples

       -X REGEXPR, --exclude=REGEXPR
              exclude  items that match given REGEXPR. You may use this option
              multiple times to build up a list of things to exclude.

              compile all files from given private directory in postinst/rtup-
              date not just the ones provided by the package (i.e. do not pass
              the --package parameter to py3compile/py3clean)

              translate given requirements into Debian  dependencies  and  add
              them   to  ${python3:Depends}.  Use  it  for  missing  items  in

              translate given requirements into Debian  dependencies  and  add
              them to ${python3:Recommends}

              do not translate shebangs into Debian dependencies
