# 'dep_list' is an array indexed by (sort-object) name
# an array element is a list with the first element being a count
# on how many other objects this object depends.
# the rest of the list enumerates the objects which depend
# on his one.
# e.g. obj1: { 0 obj2 obj3 obj4 } means
# object 1 does not depend on any other object
# object 2, 3 and 4 depend on object 1
# e.g. obj5: { 3 }
# object 5 depends on three other objects,
# no other object depends on object 5
#
# 'sorted_list' is a list of object names that can be sorted
# 'unsortables' is a list of object names that cannot be sorted due to one or
# more cycles
