+# View Compiler
+
+This directory contains an experimental compiler for layout files.
+
+It will take a layout XML file and produce a CompiledLayout.java file with a
+specialized layout inflation function.
+
+To use it, let's assume you had a layout in `my_layout.xml` and your app was in
+the Java language package `com.example.myapp`. Run the following command:
+
+    viewcompiler my_layout.xml --package com.example.myapp --out CompiledView.java
+
+This will produce a `CompiledView.java`, which can then be compiled into your
+Android app. Then to use it, in places where you would have inflated
+`R.layouts.my_layout`, instead call `CompiledView.inflate`.
+
+Precompiling views like this generally improves the time needed to inflate them.
+
+This tool is still in its early stages and has a number of limitations.
+* Currently only one layout can be compiled at a time.
+* `merge` and `include` nodes are not supported.
+* View compilation is a manual process that requires code changes in the
+  application.
+* This only works for apps that do not use a custom layout inflater.
+* Other limitations yet to be discovered.
