-# configure script for zlib.
-#
-# Normally configure builds both a static and a shared library.
-# If you want to build just a static library, use: ./configure --static
-#
-# 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)
-
-# 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.
