@@ -0,0 +1,23 @@
+Scheme 48 is an implementation of the Scheme programming language as
+described in the Revised^4 Report on the Algorithmic Language Scheme.
+It is based on a compiler and interpreter for a virtual Scheme
+machine.  The name derives from our desire to have an implementation
+that is simple and lucid enough that it looks as if it were written in
+just 48 hours.  We don't claim to have reached that stage yet; much
+more simplification is necessary.
+
+Scheme 48 tries to be faithful to the upcoming Revised^5 Scheme
+Report, providing neither more nor less in the initial user
+environment.  (This is not to say that more isn't available in other
+environments; see below.)  Support for numbers is weak: bignums are
+slow and floating point is almost nonexistent (see description of
+floatnums, below).  DEFINE-SYNTAX, LET-SYNTAX, LETREC-SYNTAX, and
+SYNTAX-RULES are supported, but not the rest of the Revised^4 Scheme
+macro proposal.
+
+Notes for FreeBSD port:  The external dynamic loading doesn't work
+properly due in part to non-portable code and limited support by
+FreeBSD for SUN dlfcn routines.  Unless you need to load external
+C code, this is a fine interpreter.
