+
+An extension that hooks into `Program.requestAssets` to commit
+changed code to Git and provide filenames based on the commit hash.
+
+## How do I use it?
+
+```kotlin
+application {
+    program {
+        extend(GitArchiver()) {
+
+
+        }
+        extend(Screenshots())
+    }
+}
+```
+Now when a screenshot is taken, first all uncommitted code is committed to git.
+The screenshot is saved with the first 7 characters of the commit hash in the filename.
