Boolean expression evaluation is explicitly treated in both
reference manual and programmers reference.

However, I'll add an explicit remark about the consequence this has for
the order of evaluation, namely that the order is guaranteed left-to-right.
(although I think this is a logical consequence of the shortcut boolean
evaluation principle)
