<div class="block">This class implements a security manager meant for usage by tasks that run inside the
Ant VM. An examples are the Java Task and JUnitTask.
The basic functionality is that nothing (except for a base set of permissions) is allowed, unless
the permission is granted either explicitly or implicitly.
If a permission is granted this can be overruled by explicitly revoking the permission.
It is not permissible to add permissions (either granted or revoked) while the Security Manager
is active (after calling setSecurityManager() but before calling restoreSecurityManager()).</div>
