+=head1 NAME
+
+guestfish - the libguestfs filesystem interactive shell
+
+=head1 SYNOPSIS
+
+ guestfish [--options] [commands]
+
+=head1 EXAMPLES
+
+=head2 From shell scripts
+
+Create a new C</etc/motd> file in a guest:
+
+ guestfish <<_EOF_
+ add disk.img
+ run
+ mount /dev/VolGroup00/LogVol00 /
+ upload new_motd /etc/motd
+ _EOF_
+
+List the LVs in a guest:
+
+ guestfish <<_EOF_
+ add disk.img
+ run
+ lvs
+ _EOF_
+
+=head2 On the command line
+
+List the LVM PVs in a guest image:
+
+ guestfish add disk.img : run : pvs
+
+Remove C</boot/grub/menu.lst> (in reality not such a great idea):
+
+ guestfish --add disk.img \
+ --mount /dev/VolGroup00/LogVol00 \
+ --mount /dev/sda1:/boot \
+ rm /boot/grub/menu.lst : \
+ sync : exit
+
+=head2 As an interactive shell
+
+ $ guestfish
+
+ Welcome to guestfish, the libguestfs filesystem interactive shell for
+ editing virtual machine filesystems.
+
+ Type: 'help' for help with commands
+ 'quit' to quit the shell
+
+ ><fs> help
+
+=head1 DESCRIPTION
+
+Guestfish is a shell and command-line tool for examining and modifying
+virtual machine filesystems. It uses libguestfs and exposes all of
+the functionality of the guestfs API, see L<guestfs(3)>.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--help>
+
+Displays general help on options.
+
+=item B<-h> | B<--cmd-help>
+
+Lists all available guestfish commands.
+
+=item B<-h cmd> | B<--cmd-help cmd>
+
+Displays detailed help on a single command C<cmd>.
+
+=item B<-a image> | B<--add image>
+
+Add a block device or virtual machine image to the shell.
+
+=item B<-m dev[:mountpoint]> | B<--mount dev[:mountpoint]>
+
+Mount the named partition or logical volume on the given mountpoint.
+
+If the mountpoint is omitted, it defaults to C</>.
+
+You have to mount something on C</> before most commands will work.
+
+If any C<-m> or C<--mount> options are given, the guest is
+automatically launched.
+
+=item B<-n> | B<--no-sync>
+
+Disable autosync. This is enabled by default. See the discussion
+of autosync in the L<guestfs(3)> manpage.
+
+=item B<-v> | B<--verbose>
+
+Enable very verbose messages. This is particularly useful if you find
+a bug.
+
+=back
+
+=head1 COMMANDS ON COMMAND LINE
+
+Any additional (non-option) arguments are treated as commands to
+execute.
+
+Commands to execute should be separated by a colon (C<:>), where the
+colon is a separate parameter. Thus:
+
+ guestfish cmd [args...] : cmd [args...] : cmd [args...] ...
+
+If there are no additional arguments, then we enter a shell, either an
+interactive shell with a prompt (if the input is a terminal) or a
+non-interactive shell.
+
+In either command line mode or non-interactive shell, the first
+command that gives an error causes the whole shell to exit. In
+interactive mode (with a prompt) if a command fails, you can continue
+to enter commands.
+
+=head1 USING launch (OR run)
+
+As with L<guestfs(3)>, you must first configure your guest by adding
+disks, then launch it, then mount any disks you need, and finally
+issue actions/commands. So the general order of the day is:
+
+=over 4
+
+=item *
+
+add or -a/--add
+
+=item *
+
+launch (aka run)
+
+=item *
+
+mount or -m/--mount
+
+=item *
+
+any other commands
+
+=back
+
+C<run> is a synonym for C<launch>. You must C<launch> (or C<run>)
+your guest before mounting or performing any other commands.
+
+The only exception is that if the C<-m> or C<--mount> option was
+given, the guest is automatically run for you (simply because
+guestfish can't mount the disks you asked for without doing this).
+
+=head1 COMMANDS
+
+=head2 help
+
+ help
+ help cmd
+
+Without any parameter, this lists all commands. With a C<cmd>
+parameter, this displays detailed help for a command.
+
+=head2 quit | exit
+
+This exits guestfish. You can also use C<^D> key.
+
+=head2 add | drive | add-drive
+
+ add filename
+
+This adds a block device to be examined or modified.
+
+=head2 cdrom | add-cdrom
+
+ cdrom iso-file
+
+This adds a CD-ROM device to be examined.
+
+=head2 alloc | allocate
+
+ alloc filename size
+
+This creates an empty (zeroed) file of the given size, and then adds
+so it can be further examined.
+
+For more advanced image creation, see L<qemu-img(1)> utility.
+
+Size can be specified (where C<nn> means a number):
+
+=over 4
+
+=item C<nn>
+
+number of kilobytes, eg: C<1440> = standard 3.5in floppy
+
+=item C<nn>K or C<nn>KB
+
+number of kilobytes
+
+=item C<nn>M or C<nn>MB
+
+number of megabytes
+
+=item C<nn>G or C<nn>GB
+
+number of gigabytes
+
+=item C<nn>sects
+
+number of 512 byte sectors
+
+=back
+
+=head2 launch | run
+
+Launch the guest so that you can issue other commands (see below).
+
+@ACTIONS@
+
+=head1 ENVIRONMENT VARIABLES
+
+=over 4
+
+=item LIBGUESTFS_DEBUG
+
+Set C<LIBGUESTFS_DEBUG=1> to enable verbose messages. This has the
+same effect as using the B<-v> option.
+
+=item LIBGUESTFS_PATH
+
+Set the path that guestfish uses to search for kernel and initrd.img.
+See the discussion of paths in L<guestfs(3)>.
