In a way I sort of agree with this but on the other hand I look at it in
this way.

1). The only time UPDATING affects you is if you are building from
ports, in a sense

2). When upgrading a port you only need the entry that effects that port
and the ports that depend on it.

3). Also when upgrading a port you only need the entries that is only
relevant up-to that version of the port you would be upgrading to.

4). Also UPDATING is only useful if you have a ports tree installed and
will be upgrading using the ports tree.


So with the above said,

1). Why should there be a tool in user-land(world) if this matter deals
directly with upgrading ports via a ports tree.

2-3). If the entry is only relevant to the version of port being
upgraded to and the ports it depends on then there should be something
available that is more local to the port being developed rather than an
outside tool.

4). If this is only relevant to when a ports tree is available and
binary packages are not being used then there is no sense in injecting
user-land tools into the world.


Conclusion & with all due respect XML & JSON along with user-land tools
are a lame temporary solution to a longer standing problem and there is
a lack of framework that allows a developer to properly inform the user
of changes that might effect an upgrade.

``bsd.updating.mk'' might be a better longer term solution that would
allow a maintainer to alert the user with a simple "All done reading ?"
and a spill of output that effects that port up-to version being
upgraded. And yes XML and-or JSON could surely play a part in this as well.
