26 <p>The <code>configure</code> script configures the source tree
27 for compiling and installing the Apache HTTP Server on your
28 particular platform. Various options allow the compilation of a
29 server corresponding to your personal requirements.</p>
31 <p>This script, included in the root directory of the source
32 distribution, is for compilation on Unix and Unix-like systems
33 only. For other platforms, see the <a href="../platform/">platform</a> documentation.</p>
