Another reader suggested I cat the file... I take it the answer is 
"no." Specifically I am looking for a quick way to see the make 
targets as 'make' would accept them while hunting for 'uninstall' and 
other surprises. I see that it gets complicated as i.e. "_legacy" is 
a legitimate target along with "buildworld." More to investigate!

My understanding of the system for the purposes of world reduction 
and custom release engineering. My work is 1/2 way to being an 
informal howto on the subject.

Thanks to all who responded.
