+## OpenAxiom's front-end consists of two parts:
+## (a) the interprerter's parser -- also referred to as new parser
+## (b) the compiler parser -- also referred to as parser
+##
+## The new parser component is always included in a running OpenAxiom
+## image. However the old parser component is so called `autoloaded'.
+## While in theory that should work, in practice it turns out that
+## people tend to override functions in the autoload part, correcting
+## bugs only there. The consequence is that the same function will
+## bahave very differently based on the history of the seesion. Ideal
+## recipe for creating heisenbugs.
+##
+## The new parser component roughtly is:
+## astr.boot dq.boot incl.boot pile.boot ptrees.boot
+## posit.boot cparse.boot format.boot cstream.boot
