Right, my concern is rather that we can't just hardcode that xgettext
call into dh_translations then, as that would overwrite a previously
generated .pot including the C++ msgids. So if "make foo.pot" or
calling intltool-update succeeds, the following xgettext call would
need to merge the i18n.tr() msgids, but take care to actually do
overwrite an old .pot file.

Title:
  Add support for the Ubuntu SDK apps to dh_translations

Status in “pkgbinarymangler” package in Ubuntu:
  Incomplete

Bug description:
  dh_translations, when it builds a POT file from the source files, invokes intltool-update, which in turn invokes xgettext to extract the translatable strings from the source files.
  By default, xgettext looks for a set of predefined keywords to identify translatable strings.
  This set of predefined keywords doesn’t include "i18n.tr", which is the function used in QML files that use the Ubuntu SDK.
  As a result, no strings are found, and no POT file is generated.

  Ideally, dh_translations should support passing (arbitrary?) extra
  options to intltool-update/xgettext. Or at least extend the default
  list of keywords to support the apps written with the Ubuntu SDK.
