+How to install PHP with the BCMath arbitrary precision math library?
+--------------------------------------------------------------------
+
+Due to license restrictions, the BC math library can no longer be distributed
+along with PHP.  The BC math library is distributed under the restrictive
+GNU Public License, and PHP is no longer distributed under that license, but
+under a less restrictive license, the PHP License.
+
+If you want to enable BC math support (recommended), all you have to do is
+simply download http://www.php.net/extra/number4.tar.gz, and untar it on the
+top level php4 directory.
+
+A typical way of doing this would be (assuming that you have lynx):
+cd ~/php4
+lynx -dump -source http://www.php.net/extra/number4.tar.gz | gzip -d | tar xvf -
