 For creating a heap image of isac see ~~/ROOT.

 For debugging see text at begin below, e.g. theory dependencies:

   ~$ evince file:///home/wneuper/.isabelle/isabisac/browser_info/Unsorted/Isac/session_graph.pdf &

 ATTENTION: no errors in this theory do not mean that there are no errors in Isac ..

 .. open theories collecting files from folders: BaseDefinitions.thy, ProgLang.thy etc.

 Errors are rigorously detected by isabelle build.

 text \<open>

   In 2002 isac already strived for floating point numbers. Since that time

   isac represents numerals as "Free", see below (*1*). These experiments are

   unsatisfactory with respect to logical soundness.

   Since Isabelle now has started to care about floating point numbers, it is high 

   time to adopt these together with the other numerals. Isabelle2012/13's numerals

   are different from Isabelle2011, see "$ISABELLE_ISAC_TEST/Tools/isac/ProgLang/termC.sml".

   The transition from "Free" to standard numerals is a task to be scheduled for 

   several weeks. The urgency of this task follows from the experience, 

   that (1.2) for "thehier" is very hard, because "num_str" seems to destroy 

   some of the long identifiers of theorems which would tremendously simplify

   building a hierarchy of theorems according to (1.2), see (*2*) below.
