What do we know about the agreement the British had with Native Americans (around the time of the American Revolution) to reserve land west of the Appalachians for indigenous ways of life?

I'm coming to this question after reading the introduction of the American Revolution wiki, which says:

For prominent land speculators and colonists such as Daniel Boone, motivation for independence manifested itself in a desire to occupy the ten million acres of rich potential farming lands west of the Appalachian Mountains, which the British Crown had reserved to allow the Native Americans tribes to practice their traditional way of life in 1763.

The "agreement" you reference is known in Canada as the Royal Proclamation of 1763. The University of British Columbia Indigenous Foundations site has a fairly good piece on it here.
