That's not entirely true. pkg_version(1) won't work without an INDEX
file.=20
In general, INDEX is used by any application that attempts to compare
the version numbers of your installed ports with the version numbers
available in the ports tree. However the INDEX file has no direct
effect on compiling or installing any particular port.
If you have some other mechanism for deciding which ports need to be
updated, then you don't need the INDEX file.
Outside the base system, portupgrade(1) et al is all about working out
which ports have updates available and updating them in the correct
order: this clearly depends fundamentally on having some sort of index
available. portupgrade(1) takes the data from the INDEX file and
stores it in a DB hash INDEX.db, so, except as an intermediate file
during index building, technically the portupgrade(1) tools don't need
the INDEX file itself either.
Cheers,
Matthew
