How much time do you have? Mine is *very* limited right now.

The URL stuff is implemented and the API functions are already using it.
Now the internal code has to be modified to do the same (that´s
primarily the SearchXXX () methods in the new directory container (the
hash) plus some methods in ppf_TGlobalData - oh, and the specialized API
code (ppf_Open.cpp, ppf_OpenDir.cpp etc).

I wanted to do at least the hash myself, because AFAIK you don´t have
the same level of "insight" of the various dependencies with that yet
(PakFile reading/writing (writing needs to be changed anyway, at least
partly) and the overall dir management). But if you plan to stay with
PFile you´ll have to gain hat insight sooner or later anyway ;)  And I´m
really short on time. And the dependencies have to be cleaned up anyway
(there´s too much tree-specific stuff outside of the tree code) ;)

If you want I can send you my current code plus a rundown of
what-does-what and what-to-care-about when I´m back home.

PFile´s C API has to be usable both from C and C++ for example.

In any case we have the "pp" prefix whih makes the namespace for API
stuff pretty unneccessary.
The namespace for internals on the other hand is useful because it
allows us to e.g. override operator new without interfering with some
custom operator new defined by the user.
