# /curr (for all nodes). The include graph is made for a searchlist [src, /,
# /dirlink]. Note that the first directory in the searchlist is relative.
# For simplicity, we consider angled resolution only. Here is a description
# of the nodes.
#
# - Nodes A, B correspond to includepaths a.h and b.h, which are relatively
# resolved because they are found in src, which means absolute
# directory /curr/src. These filepaths are thus resolved to src/a.h and
# src/b.h and their corresponding realpaths are /curr/src/a.h and
# /curr/src/b.h. The realpaths are all what is recorded in the include
# closure, because the files are relatively resolved.
#
# - Nodes C, C', and E are absolutely resolved includepaths. More
# specifically:
#
# - Nodes C and C' correspond to includepath dir/c.h and c.h, which
# during resolution were found in / and /dirlink, respectively.
# However, /dirlink is a symbolic link to /dir, which is a real
# directory, so C and C' in fact correspond to the same realpath
# namely /dir/c.h.
#
# - Node E corresponds to includepath dir/e.h and was found during
# resolution to be in /. So, the realpath of this node is /dir/e.h.
#
# - Node D is a dummy and it is not recorded in the include closure. Still,
# its non-dummy descendants are recorded.
