Eh. Sure it is. There is a reason why rulesets are written in English, not
binary.

Yay!

In my patch no set of allowed nations means all nations can use it. Then
it would have to change so that in order to allow all nations to use it,
you would have to list them all. That's duplication!

And we can't copy the nation requirements, because we may have two
different sets of nation requirements from our two requirement techs.

For example:

[advance_sauronsupernavigation]
name     = _("Sauron's Super Navigation")
req1     = "Normal Navigation"
req2     = "Sauronification"
flags    = ""
nations  = "Sauron"

[advance_sauronification]
name     = _("Sauronification")
req1     = "None"
req2     = "None"
flags    = ""
nations  = "Sauron"

[advance_aragornsupernavigation]
name     = _("Aragorn's Super Navigation")
req1     = "Normal Navigation"
req2     = "None"
flags    = ""
nation   = "Aragorn"

[advance_navigation]
name     = _("Normal Navigation")
req1     = "None"
req2     = "None"
flags    = ""
;nations  = ""

Well, I would like to keep information about techs in the tech ruleset. I
don't agree it belongs anywhere else.
