+
+A `bld` extension for generating archives.
+
+It's in an incomplete state and currently only generates ZIP archives that
+preserve the original Posix file permissions. Support for additional features
+will be added soon.
+
+The complete documentation can be found in its [javadocs](https://rife2.github.io/bld-archive/rife/bld/extension/package-summary.html).
+
+This is a short example of how to create a ZIP archive of a directory:
+
+```java
+@BuildCommand
+public void zip()
+throws Exception {
+    new ZipOperation()
+        .sourceDirectories(new File("dir/to/zip"))
+        .destinationDirectory(new File("destination/dir"))
+        .destinationFileName("archive.zip")
+        .execute();
+}
+```
