DESCRIPTION:Higher-rank graphs form a powerful framework for studying (C*-
 )algebras. As part of an ongoing effort to find groupoid models for C*-alg
 ebras of nonfinitely aligned higher-rank graphs\, we define the finitely a
 ligned 'part' of any higher-rank graph\, characterising which cylinder set
 s in the classical path space of a higher-rank graph are compact. We use t
 his to construct path and boundary-path groupoids that are ample and Hausd
 orff\, and we give a sufficient condition for their amenability.
