Open Stack

Hi,

  Recently my colleagues pointed out that gtk+ project already support
multiple pot files, it supports both _("msg") and P_("msg") notation.

  In gtk+ project, it has two directories, po for _("msg"),
po-properties for P_("msg").

  The po directory is the same as other projects, the po-properties
directory has modified the po-properties/Makefile.in.in file, to
recognize P_("msg").

  It uses "XGETTEXT_KEYWORDS = --keyword --keyword=P_" to extract the
P_("msg") messages.

  Actually this approach requires one directory for each pot file, maybe
good to not introduce many gettext directories for openstack projects.

Thanks,
  Peng Wu
