+XPP -- First pass of the SPP preprocessor.
+
+ This directory contains the Lex and C sources for the first pass of the
+preprocessor for the IRAF SPP (subset preprocessor) language. XPP takes as
+input an SPP source file and produces as output a text file which is further
+processed by RPP (the second pass) to produce Fortran.

+ * designed and which was never intended to have a long lifetime. The next
+ * step is to replace the two passes by a single program which is functionally
+ * very similar, but which is more carefully engineered and which is written
+ * in the SPP language calling IRAF file i/o. Eventually a true compiler
+ * will be written, providing many new features, i.e., structures and pointers,
+ * automatic storage class, mapped arrays, enhanced i/o support, and good
+ * compile time error checking. This compiler will also feature a table driven
