Recursivity of -r and -R in portupgrade

[Olivier Nicole]

Hi,

I am wondering is the option -R and -r are mutually recursive in
portupgrade.

That is, if the option -R applies to every ports detected by -r and
respectively if -r applies to every ports detected by -R.

Lest take the example of:

portupgrade -fRr gd

gd depends on png, does it upgrade png with portupgrade -fRr png?

php4-gd is built from gd, does it upgrade php4-gd with 
portupgrade -Rrf php4-gd? (That will in turn upgrade php, maybe 
apache...)

Best regards,

Olivier
