+# Makefile for zlib
+# Copyright (C) 1995-2005 Jean-loup Gailly.
+# For conditions of distribution and use, see copyright notice in zlib.h
+
+# To compile and test, type:
+#    ./configure; make test
+# The call of configure is optional if you don't have special requirements
+# If you wish to build zlib as a shared library, use: ./configure -s
+
+# To use the asm code, type:
+#    cp contrib/asm?86/match.S ./match.S
+#    make LOC=-DASMV OBJA=match.o
+
+# To install /usr/local/lib/libz.* and /usr/local/include/zlib.h, type:
+#    make install
+# To install in $HOME instead of /usr/local, use:
+#    make install prefix=$HOME
