"""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. The report method, which can be overridden in derived classes,
33
takes, in addition to the relative filename, a source file type, an
34
operation, and a sestination file type. Valid file types are f (file), l
35
(symlink), d (directory) and _ (non-existant). Valid operations are *
36
(modify), = (skip: same), @ (skip: symlink substitute) and # (skip:
37
ignored).
