This release of Apache supports the notion of "optional modules".
However, the server has to know which modules are compiled into it, in
order for those modules to be effective; this requires generation of a
short bit of code ("modules.c") which simply has a list of them.

If you are satisfied with our standard module set, and expect to
continue to be satisfied with it, then you can just edit the stock
Makefile and compile as you have been doing previously.  If you would
like to select optional modules, however, you need to run the
configuration script.

To do this:

1) Edit the file "Configuration".  This contains the per-machine
   config settings of the Makefile, and also an additional section at
   the bottom which lists the modules which have been compiled in, and
   also names the files containing them.  You will need to:

   a) Select a compiler, and compilation options as appropriate to
      your machine.

   b) Uncomment lines corresponding to those optional modules you wish
      to include (among the Module lines at the bottom of the file),
      or add new lines corresponding to custom modules you have written.
      (See API.html for preliminary docs on how to do that).	

      Note that DBM auth has to be explicitly configured in, if you want
      it --- just uncomment the corresponding line.

2) Run the "Configure" script:

      % Configure
      Using 'Configuration' as config file
      %

   This generates new versions of the Makefile and of modules.c.  (If
   you want to maintain multiple configurations, you can say, e.g.,

      % Configure -file Configuration.ai
      Using alternate config file Configuration.ai
      % 

3) Type "make".

The modules we place in the Apache distribution are the ones we have
tested and are used regularly by various members of the Apache
development group.  Additional modules contributed by members or third
parties with specific needs or functions are available at
<URL:http://www.apache.org/dist/contrib/modules/>.  There are
instructions on that page for linking these modules into the
core Apache code.
