+# Makefile for zlib
+# Borland C++   
+
+# This version of the zlib makefile was adapted by Chris Young for use
+# with Borland C 4.5x with the Dos Power Pack for a 32-bit protected mode
+# flat memory model.  It was created for use with POV-Ray ray tracer and
+# you may choose to edit the CFLAGS to suit your needs but the
+# switches -WX and -DMSDOS are required.
