+    this program is used to update all the auto-generated clean headers
+    used by the Bionic C library. it assumes the following:
+
+      - a set of source kernel headers is located in '../original',
+        relative to the program's directory
+
+      - the clean headers will be placed in '../arch-<arch>/asm',
+        '../common/linux', '../common/asm-generic', etc..
+
+      - if ANDROID_PRODUCT_OUT is defined in your environment, you're
+        using the Android build system, and the program will issue
+        p4 add / edit / delete commands to update the depot for you.
+        (you'll need to p4 submit manually though)
