DirEntryScanner(**kw)

Return a prototype Scanner instance for "scanning" directory Nodes for their in-memory entries

DirScanner(**kw)

Return a prototype Scanner instance for scanning directories for on-disk files

scan_in_memory(node, env, path=())

"Scans" a Node.FS.Dir for its in-memory entries.

scan_on_disk(node, env, path=())

Scans a directory for on-disk files and directories therein.

Looking up the entries will add these to the in-memory Node tree representation of the file system, so all we have to do is just that and then call the in-memory scanning function.
