+ * as modifying the License.
+ *
+ * You may add Your own copyright statement to Your modifications and

+Ant Glob support
+
+Apache Ant
+Copyright 1999-2012 The Apache Software Foundation
+-------------------------------------
+
+This project is a fork of a subset of Ant 1.8.3:
+http://ant.apache.com/
+
+Specifically, it contains the subset of Ant related to matching glob patterns
+to paths
+
+The fork was modified as follows:
+* Started with version 1.8.3
+
+* Extracted
+ org.apache.tools.ant.types.selectors.SelectorUtils
+ and then everything it transitively references that was truly needed:
+ org.apache.tools.ant.util.FileUtils,
+ org.apache.tools.ant.taskdefs.condition.Condition,
+ org.apache.tools.ant.taskdefs.condition.OS,
+ org.apache.tools.ant.BuildException
+
+* FileUtils was pruned to keep only 2 methods, which brought OS (which
+ brought Condition). In turn this brought in BuildException which was trimmed
+ up a bit (removing references to Location)
