X@t Most operating systems have a@tmulti-level structure of
X
X@t directories, and what@tare known as "subdirectories". _@hz_@ho_@ho
X
X@t offers options about using these on the add command and the
X
X@t extract command. Normally any@tdirectory information you
X
X@t specify is preserved and available for use when the files
X
X@t are extracted. By default directory information is saved
X
X@t when a file is added,@tbut not@tused when it is@textracted.
X
X@t These@tdefaults seem to represent the most common cases.

X
X
X@t When _@hz_@ho_@ho examines the@tfilenames on the command line, an
X
X@t unintuitive name matching paradigm is@tused. If the name
X
X@t contains a path delimiter, such as '/' in UNIX or '\'@tin
X
X@t MS-DOS, only the name@tas entered is matched.
X
X
X@t For example:
X@t zoo D arch src/subz.c
X
X@t Will require an exact@tmatch before the file is deleted.
X
X@t However, if you just specify a filename without a path
X
X@t delimiter, _@ha_@hl_@hl files of that name will be deleted, in@tany

X
X@t commands. One@tof these is to update an archive and delete
X
X@t the added files. This@tis a combination of the@t-update@tand
X
X@t -move@tcommands.
X
X
X@t The expert command to@tdo this@tis:
X@t zoo aunM@tarch file1 file2
X
X@t Note that this is a combination of options, 'u' to update
X
X@t files@twhich are newer@tthan what's in the archive, 'n'@tfor
X
X@t new files not@tin the archive at all, and 'M' to move the
X
X@t added@tfiles to the archive. Files which are current in the
X
X@t archive will not be replaced,@tsaving time (and if packing is
X
X@t not done, file space).

X There is a@tlimit on the number of generations of a@tfile
X
X which will@tbe kept, set on@teach individual@tfile, and by
X
X default zero. This@tdoesn't@tmean that no generations are

X saved, it means that there's no limit. There's also a limit
X
X on@tthe whole archive, called the archive limit, and that's

X set by default to one. The@tmaximum@tnumber of generations
X
X saved is the lower@tof the two limits for any given@tfile.
X
X
X There are three ways to set up an archive with generations.
X
X The simplest is to@tleave the file limits at the default
X
X (zero) and@tset the@tarchive@tlimit. What you@tdo is to create

X an@tarchive@tusing the 'a+' command to add files and@tturn on
