+# configure script for zlib. This script is needed only if
+# you wish to build a shared library and your system supports them,
+# of if you need special compiler, flags or install directory.
+# Otherwise, you can just use directly "make test; make install"
+#
+# To create a shared library, use "configure --shared"; by default a static
+# library is created. If the primitive shared library support provided here
+# does not work, use ftp://prep.ai.mit.edu/pub/gnu/libtool-*.tar.gz
+#
+# To impose specific compiler or flags or install directory, use for example:
+# prefix=$HOME CC=cc CFLAGS="-O4" ./configure
+# or for csh/tcsh users:
+# (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
+# LDSHARED is the command to be used to create a shared library
+
+# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
+# If you have problems, try without defining CC and CFLAGS before reporting
+# an error.
