+ 1.1 Building a VM with floating-point support
+ ---------------------------------------------
+ 
+ The default motlle.vmsf configuration given above has 15-bit integers only.
+ If you replace
+   <SEARCH PATH="../mate/rep-16">
+ by
+   <SEARCH PATH="../mate/rep-float">
+ and 
+   <LOAD FILE="../mate/runtime/gen/intfns.vmsf">
+ by
+   <LOAD FILE="../mate/runtime/gen/floatfns.vmsf">
+ in your .vmsf file, you get 16-bit integers and 32-bit floating-point
+ numbers, at the cost of approximately double RAM usage for your
+ data structures.
+ 
+ Finally, by default, transcendental (sin, cos, tan, etc) and other 
+ miscellaneous (sqrt, expt) procedures are not included. If you want all of
+ these, add
+   <LOAD FILE="../mate/runtime/gen/transcendentalfns.vmsf">
+ to your .vmsf file. Or you can include these procedures individually by
+ adding
+   <FUNCTION name=mXXX>
+ lines to your .vmsf file, where XXX=sin, cos, etc.
