[gentoo-pms] Slot operators for built packages

[David Leverton <levertond@googlemail.com>]

It turns out that PMS says that if the developer wants to specify a dep 
the matches a specific slot, and also that it should be locked to the 
subslot of the package matching the dep at install time, the syntax is 
:slot=, that is with the slot between the : and the =.  Also, for both 
:= and :slot= forms, when the package is installed and the dep is 
rewritten to incorporate details of the matching package, the syntax is 
:slot/subslot=, again with all the information between the : and the =.

This means that it's not possible to tell from the built package's dep 
whether it was originally := or :slot=.  Is it too late to change this, 
by moving either the developer-written or PM-written part after the =? 
If it makes a difference, I didn't find any uses of :slot= in the main 
tree, although my grep might have been wrong....
