Is there a gnome-developers-i18n-howto article?

Hello,

Is there a existing gnome-developers-i18n-howto article somewhere?
I couldn't find it in developer.gnome.org.

There is a problem in python-based applications. The programmers often
leave pure "%s" in their codes, which is not enough if multiple placeholders
be used.

i.e.
    #, python-format
    msgid "Cannot find file %s in folder %s."

According to gettext python-format definition, if we want to reorder the
placeholders, we must know the names of the variables exactly. That is:

    msgstr "Folder %(folder_name)s does not contain file %(file_name)s."

But we cannot find the name of variable without checking code :(
Could we mark it as a note to the developers somewhere?
