See readme.html for installation information.

IMathAS was written by David Lippman with partial support from the
WA State E-Learning Council, the Transition Math Project, and Pierce College.
Additional work has been supported by xyzTextbooks, Carnegie Foundation,
and Lumen Learning.

Questions written using the IMathAS language and macro libraries are 
NOT derivative works of this software, and therefore are not required

libraries or macro libraries using a license other than public-domain, 
specify the license in the library description.  Libraries distributed 
without a license statement will be assumed to be public-domain.  

It is my interpretation of the GPL (in the spirit of free software) that 
installers should not charge end-users (students) for access to IMathAS 
beyond reasonable hosting costs.
