+.Sh NAME
+.Nm mtree
+.Nd format of mtree dir hierarchy files
+.Sh DESCRIPTION
+The
+.Nm
+format is a textual format that describes a collection of filesystem objects.
+Such files are typically used to create or verify directory hierarchies.
+.Ss General Format
+An
+.Nm
+file consists of a series of lines, each providing information
+about a single filesystem object.
+Leading whitespace is always ignored.
+.Pp
+When encoding file or pathnames, any backslash character or
+character outside of the 95 printable ASCII characters must be
+encoded as a backslash followed by three
+octal digits.
+When reading mtree files, any appearance of a backslash
+followed by three octal digits should be converted into the
+corresponding character.
+.Pp
+Each line is interpreted independently as one of the following types:
+.Bl -tag -width Cm
+.It Signature
+The first line of any mtree file must begin with
+.Dq #mtree .
+If a file contains any full path entries, the first line should
+begin with
+.Dq #mtree v2.0 ,
+otherwise, the first line should begin with
+.Dq #mtree v1.0 .
+.It Blank
+Blank lines are ignored.
+.It Comment
+Lines beginning with
+.Cm #
+are ignored.
+.It Special
+Lines beginning with
+.Cm /
+are special commands that influence
+the interpretation of later lines.
+.It Relative
+If the first whitespace-delimited word has no
+.Cm /
+characters,
+it is the name of a file in the current directory.
+Any relative entry that describes a directory changes the
+current directory.
+.It dot-dot
+As a special case, a relative entry with the filename
+.Pa ..
+changes the current directory to the parent directory.
+Options on dot-dot entries are always ignored.
+.It Full
+If the first whitespace-delimited word has a
+.Cm /
+character after
+the first character, it is the pathname of a file relative to the
+starting directory.
+There can be multiple full entries describing the same file.
+.El
+.Pp
+Some tools that process
+.Nm
+files may require that multiple lines describing the same file
+occur consecutively.
+It is not permitted for the same file to be mentioned using
+both a relative and a full file specification.
+.Ss Special commands
+Two special commands are currently defined:
+.Bl -tag -width Cm
+.It Cm /set
+This command defines default values for one or more keywords.
+It is followed on the same line by one or more whitespace-separated
+keyword definitions.
+These definitions apply to all following files that do not specify
+a value for that keyword.
+.It Cm /unset
+This command removes any default value set by a previous
+.Cm /set
+command.
+It is followed on the same line by one or more keywords
+separated by whitespace.
+.El
+.Ss Keywords
+After the filename, a full or relative entry consists of zero
+or more whitespace-separated keyword definitions.
+Each such definitions consists of a key from the following
+list immediately followed by an '=' sign
+and a value.
+Software programs reading mtree files should warn about
+unrecognized keywords.
+.Pp
+Currently supported keywords are as follows:
+.Bl -tag -width Cm
+.It Cm cksum
+The checksum of the file using the default algorithm specified by
+the
+.Xr cksum 1
+utility.
+.It Cm contents
+The full pathname of a file whose contents should be
+compared to the contents of this file.
+.It Cm flags
+The file flags as a symbolic name.
+See
+.Xr chflags 1
+for information on these names.
+If no flags are to be set the string
+.Dq none
+may be used to override the current default.
+.It Cm ignore
+Ignore any file hierarchy below this file.
+.It Cm gid
+The file group as a numeric value.
+.It Cm gname
+The file group as a symbolic name.
+.It Cm md5
+The MD5 message digest of the file.
+.It Cm md5digest
+A synonym for
+.Cm md5 .
+.It Cm sha1
+The
+.Tn FIPS
+160-1
+.Pq Dq Tn SHA-1
+message digest of the file.
+.It Cm sha1digest
+A synonym for
+.Cm sha1 .
+.It Cm sha256
+The
+.Tn FIPS
+180-2
+.Pq Dq Tn SHA-256
+message digest of the file.
+.It Cm sha256digest
+A synonym for
+.Cm sha256 .
+.It Cm ripemd160digest
+The
+.Tn RIPEMD160
+message digest of the file.
+.It Cm rmd160
+A synonym for
+.Cm ripemd160digest .
+.It Cm rmd160digest
+A synonym for
+.Cm ripemd160digest .
+.It Cm mode
+The current file's permissions as a numeric (octal) or symbolic
+value.
+.It Cm nlink
+The number of hard links the file is expected to have.
+.It Cm nochange
+Make sure this file or directory exists but otherwise ignore all attributes.
+.It Cm uid
+The file owner as a numeric value.
+.It Cm uname
+The file owner as a symbolic name.
+.It Cm size
+The size, in bytes, of the file.
+.It Cm link
+The file the symbolic link is expected to reference.
+.It Cm time
+The last modification time of the file, in seconds and nanoseconds.
+The value should include a period character and exactly nine digits
+after the period.
+.It Cm type
+The type of the file; may be set to any one of the following:
+.Pp
+.Bl -tag -width Cm -compact
+.It Cm block
+block special device
+.It Cm char
+character special device
+.It Cm dir

+.Sh HISTORY
+The
+.Nm
+utility appeared in
+.Bx 4.3 Reno .
+The
+.Tn MD5
+digest capability was added in
+.Fx 2.1 ,
+in response to the widespread use of programs which can spoof
+.Xr cksum 1 .
+The
+.Tn SHA-1
+and
+.Tn RIPEMD160
+digests were added in
+.Fx 4.0 ,
+as new attacks have demonstrated weaknesses in
+.Tn MD5 .
+The
+.Tn SHA-256
+digest was added in
+.Fx 6.0 .
+Support for file flags was added in
+.Fx 4.0 ,
+and mostly comes from
+.Nx .
+The
+.Dq full
+entry format was added by
+.Nx .
+.Sh BUGS
+The requirement for a
+.Dq #mtree
+signature line is new and not yet widely implemented.
