Currently, the code is available on the base of a license agreement with the Weierstrass Institute, and it appears to be unavoidable that even in the case of academic use, a fee is raised to cover administrative expenses of the institute.
Commercial use is a very different story.
Please contact J rgen Fuhrmann for inquiries. For academic use, the source code is available without fee after conclusion of an Academic License Agreement. Please send a message to J rgen Fuhrmann to get it. Unless you request another procedure, after we have received the license agreement, we will send you the package via electronic mail. For your records, you will receive back a copy of the license signed by the WIAS administration.
