I expect to do whatever boost decides developer's should do. Any
problems with that system will not be particular to me. What I plan
to do is test against the latest version on my own machine (in the
privacy of my own home) and make my recent changes available to
anyone who wants them. It doesn't effect boost in any way.

I'll put my changes anywhere boost want's me to put them.

I'm not against independent library versioning. If thats what boost
want's to do its fine with me. I'm not sure what "versioning" means
here. Regardless what boost does, i feel its beneficial for me to test
on my own machine

If boost buy in to that fine with me. My decision accomplish the
same benefit with requiring that boost change anything. It also
will work if boost changes something in its procedure.

If they want to wait for the next "official" release its fine. My procedure
won't effect the official release date/timetable in any way.

I see this as being even more complicated than the current situation.
But anyway its totally beside my point that developers can make
their lives much easier by testing against the last release rather
than against the development tree.

hmmm - well seems like EITHER I depend upon another library
OR I don't.

LOL - nope.

But I'm not really discussing where boost should go and/or what boost
should do. My real point is that from my standpoint I can address
most of the difficulties related to boost developement by changing
my practices in a way that doesn't conflict with current or expected
boost policies. That's all I'm saying.
