Strasheela 0.8.3

Strasheela is a highly expressive constraint-based music composition system. The Strasheela user declaratively states a music theory and the computer generates music which complies with this theory.
A theory is formulated as a constraint satisfaction problem (CSP) by a set of rules (constraints) applied to a music representation in which some aspects are expressed by variables (unknowns).
Music constraint programming is style-independent and is well-suited for highly complex theories (e.g. a fully-fledged theory of harmony). The results can be output into various formats including MIDI, Lilypond, and Csound.
Enhancements:
- This release greatly extends the available documentation.
- It now comes with a tutorial (draft) and includes several examples with musical output, an explanation of their underlying music theory, remarks on their implementation, and the full source code.
- Substantial background information on Strasheela is given by a monograph.
- Also, many additions and bugfixes have been made to the system.
