-To build, just `make' it.  You will need GNU make; it probably won't work
-with any other kind of make(1).  The executable is called project1.  It
-will produce no output except for the image files scene.ppm and scene.bmp.
+To build, just `make' it.  You will need GNU make; it won't work well with
+any other kind of make(1).  Once built, the executable is called rasterize.
+
+Caveats:
+
+1. All the mangling to get the data into a form that OpenGL likes happens
+in the draw function, so it's slow.
+
+2. The shaders do Phong lighting and texture mapping, but only two lights
+are supported at a time since that's all my laptop can do with the drivers
+I'm currently using.
+
+3. The PPM importer doesn't handle comments, and the BMP importer is also
+quite picky about the depth and color space.  Of course, importing will
+fail without any useful explanation.
