+.SH NAME
+btrfs \- a toolbox to manage btrfs filesystems
+.SH SYNOPSIS
+.sp
+\fBbtrfs\fP [global] <group> [<group>...] <command> [<args>]
+.SH DESCRIPTION
+.sp
+The \fBbtrfs\fP utility is a toolbox for managing btrfs filesystems.  There are
+command groups to work with subvolumes, devices, for whole filesystem or other
+specific actions. See section \fICOMMANDS\fP\&.
+.sp
+There are also standalone tools for some tasks like \fBbtrfs\-convert\fP or
+\fBbtrfstune\fP that were separate historically and/or haven\(aqt been merged to the
+main utility. See section \fISTANDALONE TOOLS\fP for more details.
+.sp
+For other topics (mount options, etc) please refer to the separate manual
+page \fI\%btrfs(5)\fP\&.
+.SH COMMAND SYNTAX
+.sp
+Any command name can be shortened so long as the shortened form is unambiguous,
+however, it is recommended to use full command names in scripts.  All command
+groups have their manual page named \fBbtrfs\-<group>\fP\&.
+.sp
+For example: it is possible to run \fBbtrfs sub snaps\fP instead of
+\fBbtrfs subvolume snapshot\fP\&.
+But \fBbtrfs file s\fP is not allowed, because \fBfile s\fP may be interpreted
+both as \fBfilesystem show\fP and as \fBfilesystem sync\fP\&.
+.sp
+If the command name is ambiguous, the list of conflicting options is
+printed.
+.sp
+\fISizes\fP, both upon input and output, can be expressed in either SI or IEC\-I
+units (see \fI\%numfmt(1)\fP)
+with the suffix \fIB\fP appended.
+All numbers will be formatted according to the rules of the \fIC\fP locale
+(ignoring the shell locale, see \fI\%locale(7)\fP).
+.sp
+For an overview of a given command use \fBbtrfs command \-\-help\fP
+or \fBbtrfs [command...] \-\-help \-\-full\fP to print all available options.
+.sp
+There are global options that are passed between \fIbtrfs\fP and the \fIgroup\fP name
+and affect behaviour not specific to the command, e.g. verbosity or the type
+of the output.
+.INDENT 0.0

+.SH STANDALONE TOOLS
+.sp
+New functionality could be provided using a standalone tool. If the functionality
+proves to be useful, then the standalone tool is declared obsolete and its
+functionality is copied to the main tool. Obsolete tools are removed after a
+long (years) depreciation period.
+.sp
+Tools that are still in active use without an equivalent in \fBbtrfs\fP:
+.INDENT 0.0
+.TP
+.B btrfs\-convert
+in\-place conversion from ext2/3/4 filesystems to btrfs
+.TP
+.B btrfstune
+tweak some filesystem properties on a unmounted filesystem
+.TP
+.B btrfs\-select\-super
+rescue tool to overwrite primary superblock from a spare copy
+.TP
+.B btrfs\-find\-root
+rescue helper to find tree roots in a filesystem
+.UNINDENT
+.sp
+For space\-constrained environments, it\(aqs possible to build a single binary with
+functionality of several standalone tools. This is following the concept of
+busybox where the file name selects the functionality. This works for symlinks
+or hardlinks. The full list can be obtained by \fBbtrfs help \-\-box\fP\&.
+.SH EXIT STATUS
+.sp
+\fBbtrfs\fP returns a zero exit status if it succeeds. Non zero is returned in
+case of failure.
+.SH AVAILABILITY
+.sp
+\fBbtrfs\fP is part of btrfs\-progs.  Please refer to the documentation at
+\fI\%https://btrfs.readthedocs.io\fP or wiki \fI\%http://btrfs.wiki.kernel.org\fP for further
+information.
