!!DESCRIPTION |

40 |
|

|
|
|
42 |
''zip'' is a compression and file packaging utility for |
|
|
43 |
Unix, VMS, MSDOS, OS/2, Windows NT, Minix, Atari and |
|
|
44 |
Macintosh, Amiga and Acorn RISC OS. |
|
|
45 |
|
|
|
46 |
|
|
|
47 |
It is analogous to a combination of the UNIX commands |
|
|
48 |
tar(1) and compress(1) and is compatible with |
|
|
49 |
PKZIP (Phil Katz's ZIP for MSDOS systems). |
|
|
50 |
|
|
|
51 |
|
|
|
52 |
A companion program (''unzip''(1L)), unpacks ''zip'' |
|
|
53 |
archives. The ''zip'' and ''unzip''(1L) programs can |
|
|
54 |
work with archives produced by PKZIP, and PKZIP and PKUNZIP |
|
|
55 |
can work with archives produced by ''zip''. ''zip'' |
|
|
56 |
version 2.3 is compatible with PKZIP 2.04. Note that PKUNZIP |
|
|
57 |
1.10 cannot extract files produced by PKZIP 2.04 or |
|
|
58 |
''zip'' 2.3. You must use PKUNZIP 2.04g or ''unzip'' |
|
|
59 |
5.0p1 (or later versions) to extract them. |
|
|
60 |
|
|
|
61 |
|
|
|
62 |
For a brief help on ''zip'' and ''unzip,'' run each |
|
|
63 |
without specifying any parameters on the command |
|
|
64 |
line. |
|
|
65 |
|
|
|
66 |
|
|
|
67 |
The program is useful for packaging a set of files for |
|
|
68 |
distribution; for archiving files; and for saving disk space |
|
|
69 |
by temporarily compressing unused files or |
|
|
70 |
directories. |
|
|
71 |
|
|
|
72 |
|
|
|
73 |
The ''zip'' program puts one or more compressed files |
|
|
74 |
into a single ''zip'' archive, along with information |
|
|
75 |
about the files (name, path, date, time of last |
|
|
76 |
modification, protection, and check information to verify |
|
|
77 |
file integrity). An entire directory structure can be packed |
|
|
78 |
into a ''zip'' archive with a single command. Compression |
|
|
79 |
ratios of 2:1 to 3:1 are common for text files. ''zip'' |
|
|
80 |
has one compression method (deflation) and can also store |
|
|
81 |
files without compression. ''zip'' automatically chooses |
|
|
82 |
the better of the two for each file to be |
|
|
83 |
compressed. |
|
|
84 |
|
|
|
85 |
|
|
|
86 |
When given the name of an existing ''zip'' archive, |
|
|
87 |
''zip'' will replace identically named entries in the |
|
|
88 |
''zip'' archive or add entries for new names. For |
|
|
89 |
example, if ''foo.zip'' exists and contains |
|
|
90 |
''foo/file1'' and ''foo/file2'', and the directory |
|
|
91 |
''foo'' contains the files ''foo/file1'' and |
|
|
92 |
''foo/file3'', then: |
|
|
93 |
|
|
|
94 |
|
|
|
95 |
zip -r foo foo |
|
|
96 |
|
|
|
97 |
|
|
|
98 |
will replace ''foo/file1'' in ''foo.zip'' and add |
|
|
99 |
''foo/file3'' to ''foo.zip''. After this, |
|
|
100 |
''foo.zip'' contains ''foo/file1'', ''foo/file2'', |
|
|
101 |
and ''foo/file3'', with ''foo/file2'' unchanged from |
|
|
102 |
before. |
|
|
103 |
|
|
|
104 |
|
|
|
105 |
If the file list is specified as __-@__, [[Not on MacOS] |
|
|
106 |
''zip'' takes the list of input files from standard |
|
|
107 |
input. Under UNIX, this option can be used to powerful |
|
|
108 |
effect in conjunction with the find(1) command. For |
|
|
109 |
example, to archive all the C source files in the current |
|
|
110 |
directory and its subdirectories: |
|
|
111 |
|
|
|
112 |
|
|
|
113 |
find . -name |
|
|
114 |
|
|
|
115 |
|
|
|
116 |
(note that the pattern must be quoted to keep the shell from |
|
|
117 |
expanding it). ''zip'' will also accept a single dash |
|
|
118 |
( |
|
|
119 |
'' |
|
|
120 |
|
|
|

|
|
|

zip -r - . | dd of=/dev/nrst0 obs=16k |
|
|
123 |
|
|
|
124 |
|
|
|
125 |
would write the zip output directly to a tape with the |
|
|
126 |
specified block size for the purpose of backing up the |
|
|
127 |
current directory. |
|
|
128 |
|
|
|
129 |
|
|
|
130 |
''zip'' also accepts a single dash ( |
|
|
131 |

134 |
tar cf - . | zip backup - |
|
|
135 |
|
|
|
136 |
|
|
|
137 |
would compress the output of the tar command for the purpose |
|
|
138 |
of backing up the current directory. This generally produces |
|
|
139 |
better compression than the previous example using the -r |
|
|
140 |
option, because ''zip'' can take advantage of redundancy |
|
|
141 |
between files. The backup can be restored using the |
|
|
142 |
command |
|
|
143 |
|
|
|
144 |
|
|
|
145 |
unzip -p backup | tar xf - |
|
|
146 |
|
|
|
147 |
|
|
|
148 |
When no zip file name is given and stdout is not a terminal, |
|
|
149 |
''zip'' acts as a filter, compressing standard input to |
|
|
150 |
standard output. For example, |
|
|
151 |
|
|
|
152 |
|
|
|
153 |
tar cf - . | zip | dd of=/dev/nrst0 |
|
|
154 |
obs=16k |
|
|
155 |
|
|
|
156 |
|
|
|
157 |
is equivalent to |
|
|
158 |
|
|
|
159 |
|
|
|
160 |
tar cf - . | zip - - | dd of=/dev/nrst0 |
|
|
161 |
obs=16k |
|
|
162 |
|
|
|
163 |
|
|
|
164 |
''zip'' archives created in this manner can be extracted |
|
|
165 |
with the program ''funzip'' which is provided in the |
|
|
166 |
''unzip'' package, or by ''gunzip'' which is provided |
|
|
167 |
in the ''gzip'' package. For example: |
|
|
168 |
|
|
|
169 |
|
|
|
170 |
dd if=/dev/nrst0 ibs=16k | funzip | tar xvf - |
|
|
171 |
|
|
|
172 |
|
|
|
173 |
When changing an existing ''zip'' archive, ''zip'' |
|
|
174 |
will write a temporary file with the new contents, and only |
|
|
175 |
replace the old one when the process of creating the new |
|
|
176 |
version has been completed without error. |
|
|
177 |
|
|
|
178 |
|
|
|
179 |
If the name of the ''zip'' archive does not contain an |
|
|
180 |
extension, the extension ''.zip'' is added. If the name |
|
|
181 |
already contains an extension other than ''.zip'' the |
|
|
182 |
existing extension is kept unchanged. |

zip -b /tmp stuff * |

''/tmp'', copying over ''stuff.zip'' to the current |

252 |
directory when done. This option is only useful when |

Remove (delete) entries from a ''zip'' archive. For |
|
|
272 |
example: |
|
|
273 |
|
|
|
274 |
|
|
|
275 |
zip -d foo foo/tom/junk foo/harry/* |
|
|
276 |
*.o |
|
|
277 |
|
|
|
278 |
|
|
|
279 |
will remove the entry ''foo/tom/junk'', all of the files |
|
|
280 |
that start with ''foo/harry/'', and all of the files that |
|
|
281 |
end with ''.o'' (in any path). Note that shell pathname |
|
|
282 |
expansion has been inhibited with backslashes, so that |
|
|
283 |
''zip'' can see the asterisks, enabling ''zip'' to |
|
|
284 |
match on the contents of the ''zip'' archive instead of |
|
|
285 |
the contents of the current directory. |
|
|
286 |
|
|
|
287 |
|
|
|
288 |
Under MSDOS, __-d__ is case sensitive when it matches |
|
|
289 |
names in the ''zip'' archive. This requires that file |
|
|
290 |
names be entered in upper case if they were zipped by PKZIP |
|
|
291 |
on an MSDOS system. |

Do not create entries in the ''zip'' archive for |
|
|
307 |
directories. Directory entries are created by default so |
|
|
308 |
that their attributes can be saved in the zip archive. The |
|
|
309 |
environment variable ZIPOPT can be used to change the |
|
|
310 |
default options. For example under Unix with |
|
|
311 |
sh: |
|
|
312 |
|
|
|
313 |
|
|
|
314 |
ZIPOPT= |
|
|
315 |
|
|
|
316 |
|
|
|
317 |
(The variable ZIPOPT can be used for any option except |
|
|
318 |
__-i__ and __-x__ and can include several options.) |
|
|
319 |
The option __-D__ is a shorthand for __-x__ |

Encrypt the contents of the ''zip'' archive using a |
|
|
327 |
password which is entered on the terminal in response to a |
|
|
328 |
prompt (this will not be echoed; if standard error is not a |
|
|
329 |
tty, ''zip'' will exit with an error). The password |
|
|
330 |
prompt is repeated to save the user from typing |
|
|
331 |
errors. |

|

344 |
Replace (freshen) an existing entry in the ''zip'' |
|
|
345 |
archive only if it has been modified more recently than the |
|
|
346 |
version already in the ''zip'' archive; unlike the update |
|
|
347 |
option (__-u__) this will not add files that are not |
|
|
348 |
already in the ''zip'' archive. For example: |
|
|
349 |
|
|
|
350 |
|
|
|
351 |
zip -f foo |
|
|
352 |
|
|
|
353 |
|
|
|
354 |
This command should be run from the same directory from |
|
|
355 |
which the original ''zip'' command was run, since paths |
|
|
356 |
stored in ''zip'' archives are always |
|
|
357 |
relative. |
|
|
358 |
|
|
|
359 |
|
|
|
360 |
Note that the timezone environment variable TZ should be set |
|
|
361 |
according to the local timezone in order for the __-f__ , |
|
|
362 |
__-u__ and __-o__ options to work |
|
|
363 |
correctly. |
|
|
364 |
|
|
|
365 |
|
|
|
366 |
The reasons behind this are somewhat subtle but have to do |
|
|
367 |
with the differences between the Unix-format file times |
|
|
368 |
(always in GMT) and most of the other operating systems |
|
|
369 |
(always local time) and the necessity to compare the two. A |
|
|
370 |
typical TZ value is ``MET-1MEST'' (Middle European time with |
|
|
371 |
automatic adjustment for ``summertime'' or Daylight Savings |
|
|
372 |
Time). |

also removed. No deletions are done until ''zip'' has |
|

created the archive without error. This is useful for |
|
|

conserving disk space, but is potentially dangerous so it is |

|
|
|

Do not attempt to compress files named with the given |
|
|
550 |
''suffixes.'' Such files are simply stored (0% |
|
|
551 |
compression) in the output zip file, so that ''zip'' |
|
|
552 |
doesn't waste its time trying to compress them. The suffixes |
|
|
553 |
are separated by either colons or semicolons. For |
|
|
554 |
example: |
|
|
555 |
|
|
|
556 |
|
|
|
557 |
zip -rn .Z:.zip:.tiff:.gif:.snd foo |
|
|
558 |
foo |
|
|
559 |
|
|
|
560 |
|
|
|
561 |
will copy everything from ''foo'' into ''foo.zip'', |
|
|
562 |
but will store any files that end in ''.Z'', ''.zip'', |
|
|
563 |
''.tiff'', ''.gif'', or ''.snd'' without trying to |
|
|
564 |
compress them (image and sound files often have their own |
|
|
565 |
specialized compression methods). By default, ''zip'' |
|
|
566 |
does not compress files with extensions in the list |
|
|
567 |
''.Z:.zip:.zoo:.arc:.lzh:.arj.'' Such files are stored |
|
|
568 |
directly in the output archive. The environment variable |
|
|
569 |
ZIPOPT can be used to change the default options. For |
|
|
570 |
example under Unix with csh: |
|
|
571 |
|
|
|
572 |
|
|
|
573 |
setenv ZIPOPT |
|
|
574 |
|
|
|
575 |
|
|
|
576 |
To attempt compression on all files, use: |
|
|
577 |
|
|
|
578 |
|
|
|
579 |
zip -n : foo |
|
|
580 |
|
|
|
581 |
|
|
|
582 |
The maximum compression option __-9__ also attempts |
|
|
583 |
compression on all files regardless of |
|
|
584 |
extension. |
|
|
585 |
|
|
|
586 |
|
|
|
587 |
On Acorn RISC OS systems the suffixes are actually filetypes |
|
|
588 |
(3 hex digit format). By default, zip does not compress |
|
|
589 |
files with filetypes in the list DDC:D96:68E (i.e. Archives, |

Replace (update) an existing entry in the ''zip'' archive |
|
|
762 |
only if it has been modified more recently than the version |
|
|
763 |
already in the ''zip'' archive. For example: |
|
|
764 |
|
|
|
765 |
|
|
|
766 |
zip -u stuff * |
|
|
767 |
|
|
|
768 |
|
|
|
769 |
will add any new files in the current directory, and update |
|
|
770 |
any files which have been modified since the ''zip'' |
|
|
771 |
archive ''stuff.zip'' was last created/modified (note |
|
|
772 |
that ''zip'' will not try to pack ''stuff.zip'' into |
|
|
773 |
itself when you do this). |
|
|
774 |
|
|
|
775 |
|
|
|
776 |
Note that the __-u__ option with no arguments acts like |

Normally, when applied to real operations, this option |
|
|
787 |
enables the display of a progress indicator during |
|
|
788 |
compression and requests verbose diagnostic info about |
|
|
789 |
zipfile structure oddities. |
|
|
790 |
|
|
|
791 |
|
|
|
792 |
When __-v__ is the only command line argument, and stdout |
|
|
793 |
is not redirected to a file, a diagnostic screen is printed. |
|
|
794 |
In addition to the help screen header with program name, |
|
|
795 |
version, and release date, some pointers to the Info-ZIP |
|
|
796 |
home and distribution sites are given. Then, it shows |
|
|
797 |
information about the target environment (compiler type and |
|

798 |
version, OS version, compilation date and the enabled |
|

!!EXAMPLES |
|
|
912 |
|
|
|
913 |
|
|
|
914 |
The simplest example: |
|
|
915 |
|
|
|
916 |
|
|
|
917 |
zip stuff * |
|
|
918 |
|
|
|
919 |
|
|
|
920 |
creates the archive ''stuff.zip'' (assuming it does not |
|
|
921 |
exist) and puts all the files in the current directory in |
|
|
922 |
it, in compressed form (the ''.zip'' suffix is added |
|
|
923 |
automatically, unless that archive name given contains a dot |
|
|
924 |
already; this allows the explicit specification of other |
|
|
925 |
suffixes). |
|
|
926 |
|
|
|
927 |
|
|
|
928 |
Because of the way the shell does filename substitution, |
|
|
929 |
files starting with |
|
|
930 |
|
|
|
931 |
|
|
|
932 |
zip stuff .* * |
|
|
933 |
|
|
|
934 |
|
|
|
935 |
Even this will not include any subdirectories from the |
|
|
936 |
current directory. |
|
|
937 |
|
|
|
938 |
|
|
|
939 |
To zip up an entire directory, the command: |
|
|
940 |
|
|
|
941 |
|
|
|
942 |
zip -r foo foo |
|
|
943 |
|
|
|
944 |
|
|
|
945 |
creates the archive ''foo.zip'', containing all the files |
|
|
946 |
and directories in the directory ''foo'' that is |
|
|
947 |
contained within the current directory. |
|
|
948 |
|
|
|
949 |
|
|
|
950 |
You may want to make a ''zip'' archive that contains the |
|
|
951 |
files in ''foo'', without recording the directory name, |
|
|
952 |
''foo''. You can use the __-j__ option to leave off |
|
|
953 |
the paths, as in: |
|
|
954 |
|
|
|
955 |
|
|
|
956 |
zip -j foo foo/* |
|
|
957 |
|
|
|
958 |
|
|
|
959 |
If you are short on disk space, you might not have enough |
|
|
960 |
room to hold both the original directory and the |
|
|
961 |
corresponding compressed ''zip'' archive. In this case, |
|
|
962 |
you can create the archive in steps using the __-m__ |
|
|
963 |
option. If ''foo'' contains the subdirectories |
|
|
964 |
''tom'', ''dick'', and ''harry'', you |
|
|
965 |
can: |
|
|
966 |
|
|
|
967 |
|
|
|
968 |
zip -rm foo foo/tom |
|
|
969 |
zip -rm foo foo/dick |
|
|
970 |
zip -rm foo foo/harry |
|
|
971 |
|
|
|
972 |
|
|
|
973 |
where the first command creates ''foo.zip'', and the next |
|
|
974 |
two add to it. At the completion of each ''zip'' command, |
|
|
975 |
the last created archive is deleted, making room for the |
|
|
976 |
next ''zip'' command to function. |

This section applies only to UNIX. Watch this space for |

|
|
|
983 |
|
|
|
984 |
The UNIX shells (sh(1) and csh(1)) do filename |
|
|
985 |
substitution on command arguments. The special characters |
|
|
986 |
are: |
|
|
987 |
|
|
|
988 |
|
|
|
989 |
__?__ |
|
|
990 |
|
|
|
991 |
|
|
|
992 |
match any single character |
|
|
993 |
|
|
|
994 |
|
|
|
995 |
__*__ |
|
|
996 |
|
|
|
997 |
|
|
|
998 |
match any number of characters (including none) |
|
|
999 |
|
|
|
1000 |
|
|
|
1001 |
__[[]__ |
|
|
1002 |
|
|
|
1003 |
|
|
|
1004 |
match any character in the range indicated within the |
|
|
1005 |
brackets (example: [[a-f], [[0-9]). |
|
|
1006 |
|
|
|
1007 |
|
|
|
1008 |
When these characters are encountered (without being escaped |
|
|
1009 |
with a backslash or quotes), the shell will look for files |
|
|
1010 |
relative to the current path that match the pattern, and |
|
|
1011 |
replace the argument with a list of the names that |
|
|
1012 |
matched. |
|
|
1013 |
|
|
|
1014 |
|
|
|
1015 |
The ''zip'' program can do the same matching on names |
|
|
1016 |
that are in the ''zip'' archive being modified or, in the |
|
|
1017 |
case of the __-x__ (exclude) or __-i__ (include) |
|
|
1018 |
options, on the list of files to be operated on, by using |
|
|
1019 |
backslashes or quotes to tell the shell not to do the name |
|
|
1020 |
expansion. In general, when ''zip'' encounters a name in |
|
|
1021 |
the list of files to do, it first looks for the name in the |
|
|
1022 |
file system. If it finds it, it then adds it to the list of |
|
|
1023 |
files to do. If it does not find it, it looks for the name |
|
|
1024 |
in the ''zip'' archive being modified (if it exists), |
|
|
1025 |
using the pattern matching characters described above, if |
|
|
1026 |
present. For each match, it will add that name to the list |
|
|
1027 |
of files to be processed, unless this name matches one given |
|
|
1028 |
with the __-x__ option, or does not match any name given |
|
|
1029 |
with the __-i__ option. |
|
|
1030 |
|
|
|
1031 |
|
|
|
1032 |
The pattern matching includes the path, and so patterns like |
|
|
1033 |
*.o match names that end in |
|
|
1034 |
|
|
|
1035 |
|
|
|
1036 |
In general, use backslash to make ''zip'' do the pattern |
|
|
1037 |
matching with the __-f__ (freshen) and __-d__ (delete) |
|
|
1038 |
options, and sometimes after the __-x__ (exclude) option |
|
|
1039 |
when used with an appropriate operation (add, __-u__, |
|
|
1040 |
__-f__, or __-d__). |

VMS interprets standard Unix (or PC) return values as other, |
|
|
1202 |
scarier-looking things, so ''zip'' instead maps them into |
|
|
1203 |
VMS-style status codes. The current mapping is as follows: 1 |
|
|
1204 |
(success) for normal exit, and (0x7fff000? + |
|
|
1205 |
16*normal_zip_exit_status) for all errors, where the `?' is |
|
|
1206 |
0 (warning) for ''zip'' value 12, 2 (error) for the |
|
|
1207 |
''zip'' values 3, 6, 7, 9, 13, 16, 18, and 4 (fatal |
|
|
1208 |
error) for the remaining ones. |

1212 |
''zip'' 2.3 is not compatible with PKUNZIP 1.10. Use |
|
|
1213 |
''zip'' 1.1 to produce ''zip'' files which can be |
|
|
1214 |
extracted by PKUNZIP 1.10. |
|
|
1215 |
|
|
|
1216 |
|
|
|
1217 |
''zip'' files produced by ''zip'' 2.3 must not be |
|
|
1218 |
''updated'' by ''zip'' 1.1 or PKZIP 1.10, if they |
|
|
1219 |
contain encrypted members or if they have been produced in a |
|
|
1220 |
pipe or on a non-seekable device. The old versions of |
|
|
1221 |
''zip'' or PKZIP would create an archive with an |
|
|
1222 |
incorrect format. The old versions can list the contents of |
|
|
1223 |
the zip file but cannot extract it anyway (because of the |
|
|
1224 |
new compression algorithm). If you do not use encryption and |
|
|
1225 |
use regular disk files, you do not have to care about this |
|
|
1226 |
problem. |
|
|
1227 |
|
|
|
1228 |
|
|
|
1229 |
Under VMS, not all of the odd file formats are treated |
|
|
1230 |
properly. Only stream-LF format ''zip'' files are |
|
|
1231 |
expected to work with ''zip''. Others can be converted |
|
|
1232 |
using Rahul Dhesi's BILF program. This version of ''zip'' |
|
|
1233 |
handles some of the conversion internally. When using Kermit |
|
|
1234 |
to transfer zip files from Vax to MSDOS, type |
|
|
1235 |
'' |
|
|
1236 |
|
|
|
1237 |

Under VMS, zip hangs for file specification that uses DECnet |
|
|
1239 |
syntax ''foo::*.*.'' |

On OS/2, zip cannot match some names, such as those |
|
|
1243 |
including an exclamation mark or a hash sign. This is a bug |
2 |
perry |
1244 |
in OS/2 itself: the 32-bit !DosFindFirst/Next don't find such |
1 |
perry |
1245 |
names. Other programs such as GNU tar are also affected by |
|
|
1246 |
this bug. |
|
|
1247 |
|
|
|
1248 |
|
|
|
1249 |
Under OS/2, the amount of Extended Attributes displayed by |
|
|
1250 |
DIR is (for compatibility) the amount returned by the 16-bit |
2 |
perry |
1251 |
version of !DosQueryPathInfo(). Otherwise OS/2 1.3 and 2.0 |
1 |
perry |
1252 |
would report different EA sizes when DIRing a file. However, |
|
|
1253 |
the structure layout returned by the 32-bit |
2 |
perry |
1254 |
!DosQueryPathInfo() is a bit different, it uses extra padding |
1 |
perry |
1255 |
bytes and link pointers (it's a linked list) to have all |
|
|
1256 |
fields on 4-byte boundaries for portability to future RISC |
|
|
1257 |
OS/2 versions. Therefore the value reported by ''zip'' |
|
|
1258 |
(which uses this 32-bit-mode size) differs from that |
|
|
1259 |
reported by DIR. ''zip'' stores the 32-bit format for |
|
|
1260 |
portability, even the 16-bit MS-C-compiled version running |
|
|
1261 |
on OS/2 1.3, so even this one shows the 32-bit-mode |
|
|
1262 |
size. |

Thanks to R. P. Byrne for his ''Shrink.Pas'' program, |
|
|
1292 |
which inspired this project, and from which the shrink |
|
|
1293 |
algorithm was stolen; to Phil Katz for placing in the public |
|
|
1294 |
domain the ''zip'' file format, compression format, and |
|
|
1295 |
.ZIP filename extension, and for accepting minor changes to |
|
|
1296 |
the file format; to Steve Burg for clarifications on the |
|
|
1297 |
deflate format; to Haruhiko Okumura and Leonid Broukhis for |
|
|
1298 |
providing some useful ideas for the compression algorithm; |
|
|
1299 |
to Keith Petersen, Rich Wales, Hunter Goatley and Mark Adler |
|
|
1300 |
for providing a mailing list and ''ftp'' site for the |
|
|
1301 |
Info-ZIP group to use; and most importantly, to the Info-ZIP |
|
|
1302 |
group itself (listed in the file ''infozip.who'') without |
|
|
1303 |
whose tireless testing and bug-fixing efforts a portable |
|
|
1304 |
''zip'' would not have been possible. Finally we should |
|
|
1305 |
thank (blame) the first Info-ZIP moderator, David |
|
|
1306 |
Kirschbaum, for getting us into this mess in the first |
|
|
1307 |
place. The manual page was rewritten for UNIX by R. P. C. |
