+The results of an attack on a vulnerable XML library can be fairly dramatic.
+With just a few hundred Bytes of XML data an attacker can occupy several
+Gigabytes of memory within seconds.  An attacker can also keep CPUs busy for a
+long time with a small to medium size request.  Under some circumstances it is
+even possible to access local files on your server, to circumvent a firewall,
+or to abuse services to rebound attacks to third parties.  This library allows
+for XML to be parsed in a manner that avoids these pitfalls.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
