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