To recertify the exercise solutions, simply execute "make" in this directory (assuming your system understands "make"). However, in order to recertify the case study input and construct book/outline, you will have to build ACL2(r) (see :doc REAL) and proceed from under books/nonstd/workshops/1999/calculus/book/. If you do not already have that directory, you can fetch it together with all the non-standard analysis books by clicking first on "Obtaining and Installing" on the ACL2 home page, and then clicking on "OBTAINING AND INSTALLING ACL2". If you care to use the outline tool for your own work, please see the end of book/README in the above directory under the heading "USING THE PROOF OUTLINE TOOL." The exercise solutions are in subdirectory solutions/. See solutions/README. Matt Kaufmann Advanced Micro Devices, Inc. June, 2000
