Show FreeOrion Technologies

Q: What is this web-page?

A: I was trying to play FreeOrion (an open-source 4X space game) but had a tough time getting a big-picture feel for all the technologies and buildings available. One culprit is that the in-game "research" pane shows all technologies with not enough rhyme or reason in organizing related technologies to be together. So I threw together a web script that shows the same technologies (plus buildings, ship parts, etc) in a slightly more organized way.

Anyhoo, if you play FreeOrion feel free to search-by-technology here.

(note: this page is a work-in-progress. there's stuff I've been meaning to add, and bugs I've been meaning to fix...)

Which Technologiess to Show Show _all_ technologies as one big (but slightly hard to comprehend) group:
    All Technologies

Do a little searching, and show these:
    All Growth items
    All Learning items
    All Construction/Production items
    All Defense items (to protect planet)
    All Offense items (to outfit warships)
    All Intelligence (Stealth) items
    All Intelligence (Detection) items

    Just Shipyards and Hulls
    Shipyards, Hulls, and related technologies

Show me the tree for this technology (can use comma-separated names):

    Or for one of these these top-level technologies:
    Aggression
    Algorithmic Elegance
    Armor Plating
    Asymptotic Materials
    Deception
    Empire Intelligence Agency
    Galactic Exploration
    Genetic Engineering
    Orbital Construction
    Planetary Ecology
    Predictive Stockpiling
    Robotic Production
    Self Defense
    The Physical Brain

Show me techs that can be unlocked next, given that these are already unlocked:
        (add already-unlocked techs in the box, can be comma- or newline-separated names)
        (techs unlocked at the start of the game like "Self Defense" are implicitly added to the box)
    Show this many levels of tech that are next to be unlocked:


(include buildings/spaceship-hulls/etc in these technologies)
(show the technologies above as one big group instead of separated into groups)
