"Oil is an extension to [Tcl] which provides a high-level method to control
graphics, effects and other media systems. My long-term goal is for Oil
to do to [SDL]-coding what [Tk] did for [X]-coding."

[PT] 18-Jul-2003: Liboil can be built for windows using the mingw compiler. You need to get the SDL
development library for mingw from the SDL site [http://www.libsdl.org/] and apply the following patch
to the current Makefile in liboil. What you end up with is a ''oilsh'' shell. This isn't too good as
an interactive shell under windows - but it does successfully run the oil scripts. Try the managers
demo mentioned above.

To use this patch, copy it to a file and delete the leading single space (for instance, in emacs use
M-x replace-regexp<RET>^ <RET><RET>). You'll need to edit the location of your SDLDIR - and the SDL include directory needs to be renamed from include to SDL (because all the #includes are for <SDL/xxxx.h>).

This has obviously nothing to do with libOil from http://www.schleef.org/liboil/ except the name collision (that seems to be their fault this time).

Is there anything for Tcl to gain from optimized inner loops library?
