Archive N levels of a directory.
NK=nk Number of extra copies to keep.
CURR=curr Name of current data directory.
BASE=base Base name of archive copies.
/QUIET give less feedback.
/VERBOSE give more feedback.
Notes: Current directory, curr, will be copied to the
base_0 archive directory. Example:
If nk=3, curr='data', and base='data_' and
there are 3 archive directories (the max number), then
data_3 will be deleted,
data_2 will move to data_3
data_1 will move to data_2
data_0 will move to data_1
data will copy to data_0
This routine could be called after new content is created
in the current directory.
