As dynamic memory allocation is used throughout the program, the size of the data is constrained only by the available memory. Furthermore, due to the standard Windows interface, the software package becomes more user-friendly. This fee is mainly to support my work and to buy new computer hard- and software, and additionally to defray the costs of diskettes and mailing expenses. The fee should be paid only once and includes updates and new releases of the package. However, I will try to further improve the package and to add interesting features.
All suggestions are very welcome.
Special thanks also to Peter De Rijk for his help in some programmatorical problems and Gert Van der Auwera for his help in drawing unrooted trees. James S. Farris is greatly acknowledged for sharing his code to convert trees saved in the New Hampshire bracket format. I also want to thank all other individuals who made helpful suggestions, reported bugs, and stimulated me in this work. Of course, a user manual is never complete. Some inaccuracies may exist while a few sections may be too brief or missing.
