Acro User Manual Version Version 1.0

## Acknowledgements

The Acro Project grew out of the ongoing development of the UTILIB, SGOPT, Coliny, and PICO libraries within the Discrete Algorithms and Mathematics Department. In particular, the development of PICO and Coliny increasingly required the integration of third-party libraries. Although a variety of people have contributed to the Acro packages, I would like to thank Cindy Phillips, Jonathan Eckstein, Mario Alleva, Shannon Brown and Mike Eldred for their input on these software libraries, which ultimately influenced the design of Acro itself. The design of Acro has been significantly influenced by their feedback.
