Red Hat SELinux Application Development Guide?

[Benjamin Tsai]

I googled-out this document for writing selinux-aware software
application, but can't find any of a link from RedHat.

Does this document exist? Besides, is there any tutorial for writing
selinux-aware programs? 

I have read "Red Hat SELinux Guide", NSA "Implementing SELinux as a
Linux Security Module," ... and some other documents about writing
selinux policy.

But still don't get it how to write such a program. Please give me some
directions. Thx.
