+This directory is to contain the source for a basic motion tracker.
+The goal should be to make it not specific to Aegisub, but generally
+re-usable in other projects as well.
+
+It should probably be as modular as reasonably possible:
+- Publish functions for creating some basic data structures, like:
+  o Trackpoints
+  o Image scale spaces (?)
+  o Other?
+- Functions for basic manipulations:
+  o Generate track points from an image, with a choice of algorithm
+  o Track one point from one image to the next, also algorithm choice
+  o More?
+- Packaged all-in-one operations
+  o Something (callback based?) that generates a series of track points
+    tracked along a series of images
+
+I guess it might become a bit like FFTW is for fourier transforms, if
+this succeeds.
+
+Code should, of course, be well commented.
+
+Should not depend on wxWidgets (cf. "not specific to Aegisub") and
+should overall be as independent as possible.
