"""The copy-base walker traverses a walklist ruthlessly mirroring src to dst.
30
29
It is designed to be the base class of both the copy-in and copy-out walker,
31
30
both of which are specialisations of this purpose. See them for more
32
information.
31
information. The print_op method, derived in those classes, takes, in
32
addition to the relative filename, a source file type, an operation, and a
33
sestination file type. Valid file types are f (file), l (symlink), d
34
(directory) and _ (non-existant). Valid operations are * (modify), = (skip:
35
same), @ (skip: symlink substitute) and # (skip: ignored).
