.SH DESCRIPTION
39 
These commands interpret data from traditional tape or file system formats
40 
stored in
41 
.IR file ,
42 
and mount their contents (read-only) into a Plan 9 file system.
43 
The optional
44 
.B -p
45 
and
46 
.B -g
47 
flags specify Unix-format password (respectively group) files
48 
that give the mapping between the numeric user- and group-ID
49 
numbers on the media and the strings reported by Plan 9 status
50 
inquiries.
51 
The
52 
.B -m
53 
flag introduces the name at which the new file system should be
54 
attached; the default is
55 
.BR /n/tapefs .
56 
.PP
57 
.I 32vfs
58 
interprets raw disk images of 32V systems, which are ca. 1978 research Unix systems for
59 
the VAX (512 byte block size, the default), and also pre-FFS Berkeley VAX systems (1KB block size).
60 
.PP
61 
.I Cpiofs
62 
interprets
63 
.B cpio
64 
tape images (constructed with
65 
.BI cpio 's
66 
.B c
67 
flag).
68 
.PP
69 
.I Tarfs
70 
interprets
71 
.I tar
72 
tape images.
73 
.PP
74 
.I Tpfs
75 
interprets
76 
.I tp
77 
tapes from the Fifth through Seventh Edition research Unix systems.
78 
.PP
79 
.I Tapfs
80 
interprets
81 
.I tap
82 
tapes from the pre-Fifth Edition era.
83 
.PP
84 
.I V6fs
85 
interprets disk images from the
86 
Fifth and Sixth edition research Unix systems (512B block size).
87 
.PP
88 
.I V10fs
89 
interprets disk images from the
90 
Tenth Edition research Unix systems (4KB block size).
91 
.PP
92 
.I Zipfs
93 
interprets zip archives (see
94 
.IR gzip (1)).
95 
.SH SOURCE
96 
.PP
97 
These commands are constructed in a highly stereotyped
98 
way using the files
99 
.I fs.c
100 
and
101 
.I util.c
102 
in
103 
.BR /sys/src/cmd/tapefs ,
104 
which in
105 
turn derive substantially from
106 
.IR ramfs (4).
