* Adjust debpython/depends.py to be multiarch-friendly.

dependencies are just an info now

  * Fix some lintian warnings.

  * Drop python2.6 as a supported python version.
  * Bump standards version to 3.9.4.
  * Start building the libpython-stdlib, libpython-all-dev, libpython-all-dbg
    packages.

dh_python2: generates correct "python (<< 2.X)" dependencies for packages with private Python extensions

require.txt items that have a pydist file with (uscan like) rules
or PEP386 flag (Closes: #653740)

DEBPYTHON_SUPPORTED and DEBPYTHON_DEFAULT is used in tests instead

can be used to override list of supported/default Python versions in Debian

  - rewrite shebangs by default (disable via --no-shebang-rewrite),
    examples:
     + "/usr/bin/env python*" → "/usr/bin/python*"
     + "/usr/local/bin/python foo" → "/usr/bin/python foo"
     + "/usr/bin/python2" → "/usr/bin/python"
  - new --shebang option to replace all shebangs in bin dirs
    (example: --shebang /usr/bin/python2.6)

    (Closes: #657665)

with all Python versions

version only (closes: #644573)

(and let debhelper warn about it, it's not our job)

(closes: 636255)

    to stderr (LP: #812960)

  - generates rtupdate scripts for private directories that compile files
    from given package only, add --compile-all to dh_python2's call if you
    want the old behaviour (i.e. compile also files (plugins?) provided by
    other packages, which do not use a helper/bytecompile them)
* pyclean now accepts --package and private dir argument at the same time

creation, use "--namespace bar.foo" instead

(it is replaced with python-pkg-resources Debian dependency)

shebangs, byte-compile the dir with default Python version (or the one
requested via X-Python-Version) instead od failing. Add dependency for
each (supported) interpreter detected in shebangs
