NAME

       dh_python2  -  calculates  Python  dependencies,  adds  maintainer scripts to byte compile
       files, etc.

SYNOPSIS

          dh_python2 -p PACKAGE [-V [X.Y][-][A.B]] DIR_OR_FILE [-X REGEXPR]

DESCRIPTION

   QUICK GUIDE FOR MAINTAINERS
          · if necessary, describe  supported  Python  versions  via  X-Python-Version  field  in
            debian/control,

          · build-depend on python or python-all or python-all-dev (>= 2.6.6-3~),

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

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

          · add python2 to dh's --with option, or:

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

          · call dh_python2 in the binary-* target,

          · add ${python:Depends} to Depends

   NOTES
       In order to support more than one Python version in the same  binary  package,  dh_python2
       (unlike  dh_pycentral  and dh_pysupport) creates symlinks to all supported Python versions
       at build time. It means binNMU (or sourceful upload in case  of  architecture  independent
       packages)  is required once a list of supported Python version is changed. It's faster and
       more robust than its competitors, though.

   dependencies
       dh_python2 tries to  translate  Python  dependencies  from  requires.txt  file  to  Debian
       dependencies.  Use  debian/pydist-overrides or --no-guessing-deps option to override it if
       the guess is incorrect. If you want dh_python2 to generate more strict dependencies  (f.e.
       to     avoid     ABI     problems)     create     debian/python-foo.pydist    file.    See
       /usr/share/doc/python-doc/README.PyDist  (provided  by  python-doc   package)   for   more
       information.  If  the  pydist  file  contains  PEP386  flag  or set of (uscan like) rules,
       dh_python2 will  make  the  depedency  versioned  (version  requirements  are  ignored  by
       default).

   namespace feature
       dh_python2  parses  Egg's namespace_packages.txt files (in addition to --namespace command
       line argument(s)) and drops empty __init__.py files from binary  package.  pycompile  will
       regenerate them at install time and pyclean will remove them at uninstall time (if they're
       no longer used in installed packages). It's still a good idea to provide __init__.py  file
       in one of binary packages (even if all other packages use this feature).

   private dirs
       /usr/share/foo,   /usr/share/games/foo,   /usr/lib/foo   and   /usr/lib/games/foo  private
       directories are scanned for Python files by default (where foo is binary package name). If
       your package is shipping Python files in some other directory, add another dh_python2 call
       in debian/rules with directory name as an argument - you can use different set of  options
       in this call. If you need to change options (f.e. a list of supported Python versions) for
       a private directory that is checked by  default,  invoke  dh_python2  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/python2.X/{site,dist}-packages/ directory that have extensions different 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 for all
       requested Python versions (dh_install doesn't know about python's site- vs.  dist-packages
       issue).

       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 location (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.

       Examples:

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

              · foo/bar.py 2.6- installs .../dist-packages/foo/bar.py for versions >= 2.6

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

              · debian/*.py spam.egg 2.5 installs .../python2.5/site-packages/spam/egg/*.py files

   pyremove files
       If you want to remove some files installed by build  system  (from  all  supported  Python
       versions or only from a subset of these versions), add them to debian/pkg.pyremove file.

       Examples:

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

              · bar/baz.py 2.5 removes .../python2.5/site-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 DEBPYTHON_SUPPORTED and/or
       DEBPYTHON_DEFAULT env. variables.

       Example: 2.5,2.7 limits the list of supported Python versions to  Python  2.5  and  Python
       2.7.

OPTIONS

       --version
              show program's version number and exit

       -h, --help
              show help message and exit

       --no-guessing-versions
              disable guessing other supported Python versions

       --no-guessing-deps
              disable guessing dependencies

       --no-shebang-rewrite
              do not rewrite shebangs

       --skip-private
              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 versions. See pycompile(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
              compile all files from given private directory in postinst/rtupdate  not  just  the
              ones  provided  by  the  package  (i.e.  do  not  pass  the  --package parameter to
              pycompile/pyclean)

       --depends=DEPENDS
              translate  given  requirements  into  Debian   dependencies   and   add   them   to
              ${python:Depends}. Use it for missing items in requires.txt

       --recommends=RECOMMENDS
              translate   given   requirements   into   Debian   dependencies  and  add  them  to
              ${python:Recommends}

       --suggests=SUGGESTS
              translate  given  requirements  into  Debian   dependencies   and   add   them   to

              complete

       --ignore-namespace
              ignore Egg's namespace declaration and --namespace option. This option will disable
              removing  (and  recreating  at  install  time)  empty  __init__.py  files. Removing
              namespace_packages.txt from egg-info directory has the same effect.

       --clean-pycentral
              generate maintainer script that will remove byte code generated  by  python-central
              helper

       --shebang=COMMAND
              use given command as shebang in scripts

       --ignore-shebangs
              do not translate shebangs into Debian dependencies
