+#
+# This class is intended to build pure Java packages from the sources exported
+# from the source:jar goal of Maven 2. These archives contain bare Java source
+# files, with no build instructions or additional resource files. They are
+# unsuitable for packages that require resources besides compiled class files.
+# The benefit is that for artifacts developed with Maven, these source files
+# are often released together with binary packages, whereas the full build
+# environment might be contained in some revision control system or not
+# available at all.
