     11     this program is used to update all the auto-generated clean headers
     12     used by the Bionic C library. it assumes the following:
     13 
     14       - a set of source kernel headers is located in '../original',
     15         relative to the program's directory
     16 
     17       - the clean headers will be placed in '../arch-<arch>/asm',
     18         '../common/linux', '../common/asm-generic', etc..
     19 
     20       - if ANDROID_PRODUCT_OUT is defined in your environment, you're
     21         using the Android build system, and the program will issue
     22         p4 add / edit / delete commands to update the depot for you.
     23         (you'll need to p4 submit manually though)
