System includes (summary)

[vbar]

Hi,

to summarize the solution to my problem (thanks for all your 
answers - cons isn't something I could figure out on my own),
for the purposes of dependency analysis, the Objects method
(used, in my case, by Library method) considers included files 
found in one of the directories specified in CPPPATH, whether
those files were included using quotes of angle brackets.

The Objects method may consider additional files (i.e. files 
included using quotes and found in one of the directories 
specified in the INCLUDE key of ENV), but as long as my scripts 
use CPPPATH correctly, I don't need to know...

And it's documented behavior... In fact, it's a FAQ (6.6),
except in my case, the file wasn't outside the local build 
directory... I will read the docs before posting questions...
