   The _configure_ shell script attempts to guess correct values for various
   system-dependent variables used during compilation. It uses those values to
   create a `Makefile' and a `config.h' file containing system-dependent
   definitions. __Finally, it creates a shell script `config.status' that you
   can run in the future to recreate the current configuration, a file
   `config.cache' that saves the results of its tests to speed up
   reconfiguring, and a file `config.log' containing compiler output (useful
   mainly for debugging _configure_).
   
BUILDING ON WINDOWS

   Building on Windows is somewhat different than building on Unix. We
   therefore have a separate set of directions for doing this. We maintain a
   set of Microsoft Visual C make files which can be used directly if you want
   to use this compiler. We do not support help on any type of Windows based
   compiler including msvc, so be warned!
   
      Library make file
      
      PICS Library make file
      
      Robot Makefile
      
      Line Mode Browser Makefile
      
   Stop here and jump to the Known Bugs and Patches page to see if you need to
   apply any patches before you compile. You can find some options determining
   how libwww is going to be compiled in the special windows config.h file.
   
  ZLib Support
  
   One of the options in the windows config.h file is to determine whether you
   want to use the zlib library for handling the _deflate_ content-encoding.
   This may cause better performance as we then can inflate a compressed
   document on the fly. A version of the precompiled zlib DLL for Win32 is
   already included in the w3c-libwww distribution file and you can find it in
   
        .../w3c-libwww-5.1/Library/External

   Make sure that your system knows about DLLs in this directory or that you
   move the zlib.dll to another location. Otherwise you will not be able to run
   the application as zlib DLL can not be found.
   
  Detailed Installation
  
   If you are interested in the details of how we build libwww on windows then
   please continue by reading the special documentation on how to install on
   Windows.
   
BUILDING ON UNIX

   NoteYou probably need the GNU version of make in order to build libwww. The
   reason is that some of the make files contain some syntax that most other
   makefiles don't understand.
   
   The simplest way to compile this package on a Unix platform is:
   
      `cd' to the directory containing the package's source code and type
      `./configure' to configure the package for your system. If you're using
      `csh' on an old version of System V, you might need to type `sh
      ./configure' instead to prevent `csh' from trying to execute _configure_
      itself. Running _configure_ takes awhile. While running, it prints some
      messages telling which features for which it is checking.
      
      Stop here and jump to the Known Bugs and Patches page to see if you need
      to apply any patches before you compile.
      
      Type `make' to compile the package.
      
      Type `make install' to install the library.
      
      You can remove the library and object files from the source directory by
      typing `make clean.' To also remove the files that _configure_ created
      (so you can compile the package for a different kind of computer), type
      `make distclean.'
      
COMPILERS AND OPTIONS

   Some systems require unusual options for compilation or linking that the
   _configure_ script does not know about. You can give _configure_ initial
   values for variables by setting them in the environment. Using a
   Bourne-compatible shell, you can do that on the command line like this:
   
     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure

   Or on systems that have the `env' program, you can do it like this:
   
     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure

USING A DIFFERENT BUILD DIRECTORY

   You can compile the package in a directory different from the one containing
   the source code. Doing so allows you to compile it on more than one kind of
   computer at the same time. To do this, you must use a version of `make' that
   supports the `VPATH' variable, such as GNU `make.' `cd' to the directory
   where you want to object files and library to go and run the _configure_
   script (i.e., go `../src/configure'). _configure_ automatically checks for
   source code in the directory that _configure_ is in and in `..' as well.
   
INSTALLATION NAMES

   By default, `make install' will install the library in `/usr/local/lib'. You
   can specify an installation prefix other than `/usr/local' by giving
   _configure_ the option `--prefix=PATH'. You can cause the library to be
   installed with an extra prefix or suffix on its name by giving _configure_
   the options `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
   
OPTIONAL FEATURES AND PACKAGES

   There are a set of options you can give to _configure_ in addition to those
   understood by all GNU Autoconf _configure_ scripts:
   
  --disable-FEATURE      do not include FEATURE (same as --enable-FEATURE=no)
                         
  --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
                         
  --with-PACKAGE[=ARG]   use PACKAGE [ARG=yes]
                         
  --without-PACKAGE      do not use PACKAGE (same as --with-PACKAGE=no)
                         
  --x-includes=DIR       X include files are in DIR
                         
  --x-libraries=DIR      X library files are in DIR
                         
   --enable and --with options recognized:
   
  --with-x               use the X Window System
                         
  --with-wais[=PATH]     Compile with support for direct WAIS access. This may
                         be a bit rusty!!!
                         
  --with-zlib[=PATH]     Compile with zlib compress/decompress support.
                         
  --with-socks           Compile with SOCKS firewall traversal support.
                         
  --with-socks5[=PATH]   Compile with SOCKS5 firewall traversal support.
                         
  --with-socks4[=PATH]   Compile with SOCKS4 firewall traversal support.
                         
  --enable-signals       use internal libwww signal handler.
                         
  --disable-nagle        Turning off Nagle's algorithm.
                         
  --disable-pipelining   Turning off HTTP/1.1 Pipelining.
                         
  --enable-reentrant     define _REENTRANT to enable reentrant system calls
                         
  --enable-posix         define _POSIX_SOURCE
                         
  --enable-cyrillic      include support for Cyrillic in line mode browser
                         
SPECIFYING THE SYSTEM TYPE

   There may be some features _configure_ can not figure out automatically, but
   needs to determine by the type of host the package will run on. Usually
   _configure_ can figure that out, but if it prints a message saying it can
   not guess the host type, give it the `--host=TYPE' option. TYPE can either
   be a short name for the system type, such as `sun4', or a canonical name
   with three fields:
   
     CPU-COMPANY-SYSTEM

   See the file `config.sub' for the possible values of each field. If
   `config.sub' isn't included in this package, then this package doesn't need
   to know the host type.
   
   If you are building compiler tools for cross-compiling, you can also use the
   `--target=TYPE' option to select the type of system they will produce code
   for and the `--build=TYPE' option to select the type of system on which you
   are compiling the package.
   
SHARING DEFAULTS

   If you want to set default values for _configure_ scripts to share, you can
   create a site shell script called `config.site' that gives default values
   for variables like `CC', `cache_file', and `prefix'. _configure_ looks for
   `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it
   exists. Or, you can set the `CONFIG_SITE' environment variable to the
   location of the site script. A warning: not all _configure_ scripts look for
   a site script.
   
OPERATION CONTROLS

   _configure_ recognizes the following options to control how it operates.
   
  --cache-file=FILE      Save the results of the tests in FILE instead of
                         `config.cache'. Set FILE to `/dev/null' to disable
                         caching, for debugging _configure_.
                         
  --help                 Print a summary of the options to _configure_, and
                         exit.
                         
  --quiet, --silent      Do not print messages saying which checks are being
                         made.
                         
  --srcdir=DIR           Look for the package's source code in directory DIR.
                         Usually _configure_ can determine that directory
                         automatically.
                         
  --version              Print the version of Autoconf used to generate the
                         _configure_ script, and exit.
                         
   _configure_ also accepts some other, not widely useful, options.
