<h3 id="notes-env">Notes about environment variables</h3>
-<p>Ant runs on Java 1.2 therefore it cannot use Java 5 features for accessing
environment
-variables. So it starts a command in a new process which prints the
environment variables, analyzes
-the output and creates the properties.<br/> There are commands for the
following operating systems

+<p>
+ When Ant started to support setting properties from environment
+ variables it ran on Java 1.2 where <code class="code">System.getEnv</code>
didn't
+ work. So we decided to start a command in a new process which prints
+ the environment variables, analyzes the output and creates the
+ properties. Once Java 5 became our baseline we could have switched
+ to <code class="code">getEnv</code> but it returned different results on some
+ platforms so we stuck with the command approach to remain backwards
+ compatible.
