Tools from Pugh et al.'s "Omega Project" for constraint-based compiler tools: The "Omega Library" for constraint manipulation; The "Omega Calculator" (text interface); the "Omega Test" for depedence analysis; the "Uniform Library" for code transformation; and the "Code generation" library for generating the transformed code. I am experimenting with tracking bugs with Lighthouse, but am not yet sure I've got it configure right --- see http://davew_haverford.lighthouseapp.com/projects/13658-the-omega-project/overview (if you can; if you can't, email davew@cs.haverford.edu).

README
Omega Project Source Release, version 2.1
This is verion 2.1 of the Omega Project software, including:
* The Omega library, a set of routines for manipulating linear constraints
over integer variables, Presburger formulas, and Integer tuple
relations and sets.
* The code generation library, a set of routines for generating code to
scan the points in the union of a number of convex sets.
* The Omega calculator, a text-based interface to the Omega library
* Petit, a educational/research tool for analyzing array data dependences
* The Uniform library, a source to source parallelizing transformation
system, described in Wayne Kelly's Ph.D. dissertation.
Many new features have been added, and numerous bugs fixed, by a
number of groups since the August 2000 version 1.2 from the cs.umd.edu
web site. A quick check of the omega calculator regression tests indicates
that there is one difference in the generated code for a time-skewed example,
but this may just be an equivalent iteration space expressed in a different
way.
Those who have made contributions may wish to describe them here:
