+1 It is impossible to reverse reasons based on initial statements like "This is used to track packages during Python transitions, and is also used by some packaging scripts to automatically generate appropriate Depends and Provides lines." What is the process of "tracking packages"? Any examples? Even if Depends and Provides are automatically generated developer still supply X-...-Python headers manually, so this add nothing more than another level of indirection with some bit of uncertainty to maintainer's mind. Quiting further from http://www.debian.org/doc/packaging-manuals/python-policy/ch-module_packages.html#s-specifying_versions -- cut here --- Your control file should also have a line: XB-Python-Version: ${python:Versions} The python:Versions is substituted by the supported Python versions of the binary package, based on XS-Python-Version. (If you are not using dh_python you will need to handle this substitution yourself.) The format of the field XB-Python-Version is the same as the XS-Python-Version field for packages not containing extensions. Packages with extensions must list the versions explicitely. --- cut here --- It does tell what spell to weave, but does not explain what problem it is aimed to solve. Is it solely for copying Depends field from source package to binary? I do not get some aspects of Python packaging in Debian mostly because there are many thing that people take for granted (and also because the lack of time to read out all the stuff). I would be grateful if you spot any such thing in my point of view and could explain them or point to the exact place in docs.
