This module provides the SWI-Prolog `make' facility that synchronises
Prolog internal database after loaded files have been edited.
@bug Dependency tracking is incomplete. Notably, there is no
dependency tracking if compilation of one module depends
on goal_expansion/2 or term_expansion/2 rules provided by
another.
