    USE_PERLIO  - The primary Configure variable that enables PerlIO.
                  If USE_PERLIO is _NOT_ set
                    then USE_STDIO above will be set to be conservative.
-                 If USE_PERLIO is set
-                   then there are two modes determined by USE_SFIO:
-
-   USE_SFIO    - If set causes PerlIO_xxx() to be #define-d onto sfio functions.
-                 A backward compatability mode for some specialist applications.
-
-                 If USE_SFIO is not set then PerlIO_xxx() are real functions
+                 PerlIO_xxx() are real functions
                  defined in perlio.c which implement extra functionality
                  required for utf8 support.
