groff 1.23.0 added .MR to its -man macro package. The NEWS file states
that the inclusion of the macro "was prompted by its introduction to
Plan 9 from User Space's troff in August 2020." From d32deab it seems
that the name for Plan 9 from User Space's implementation was suggested
by groff maintainer G. Brandon Robinson.
Not sure if the intention was to make these definitions compatible, but
it would be nice if they were.
Currently, Plan 9 from User Space's .MR expects its second argument to
be parenthesized. groff's .MR does not. This results in extra
parentheses appearing in manual references when viewing Plan 9 from User
Space's manual pages on a system using groff.

.SH DESCRIPTION
|
|
These commands interpret data from traditional tape or file system formats
|
|
stored in
|
|
.IR file ,
|
|
and mount their contents (read-only) into a Plan 9 file system.
|
|
The optional
|
|
.B -p
|
|
and
|
|
.B -g
|
|
flags specify Unix-format password (respectively group) files
|
|
that give the mapping between the numeric user- and group-ID
|
|
numbers on the media and the strings reported by Plan 9 status
|
|
inquiries.
|
|
The
|
|
.B -m
|
|
flag introduces the name at which the new file system should be
|
|
attached; the default is
|
|
.BR /n/tapefs .
|
|
.PP
|
|
.I 32vfs
|
|
interprets raw disk images of 32V systems, which are ca. 1978 research Unix systems for
|
|
the VAX (512 byte block size, the default), and also pre-FFS Berkeley VAX systems (1KB block size).
|
|
.PP
|
|
.I Cpiofs
|
|
interprets
|
|
.B cpio
|
|
tape images (constructed with
|
|
.BI cpio 's
|
|
.B c
|
|
flag).
|
|
.PP
|
|
.I Tarfs
|
|
interprets
|
|
.I tar
|
|
tape images.
|
|
.PP
|
|
.I Tpfs
|
|
interprets
|
|
.I tp
|
|
tapes from the Fifth through Seventh Edition research Unix systems.
|
|
.PP
|
|
.I Tapfs
|
|
interprets
|
|
.I tap
|
|
tapes from the pre-Fifth Edition era.
|
|
.PP
|
|
.I V6fs
|
|
interprets disk images from the
|
|
Fifth and Sixth edition research Unix systems (512B block size).
|
|
.PP
|
|
.I V10fs
|
|
interprets disk images from the
|
|
Tenth Edition research Unix systems (4KB block size).
|
|
.PP
|
|
.I Zipfs
|
|
interprets zip archives (see
|
|
.MR gzip 1 ).
|
|
.SH SOURCE

|
|
These commands are constructed in a highly stereotyped
|
|
way using the files
|
|
.I fs.c
|
|
and
|
|
.I util.c
|
|
in
|
|
.BR \*9/src/cmd/tapefs ,
|
|
which in
|
|
turn derive substantially from
|
|
.MR ramfs 4 .
