+-# 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.
