-.Sh NAME
-.Nm mg
-.Nd emacs-like text editor
-.Sh SYNOPSIS
-.Nm mg
-.Op Fl n
-.Op Fl f Ar mode
-.Op + Ns Ar number
-.Op Ar
-.Sh DESCRIPTION
-.Nm
-is intended to be a small, fast, and portable editor for
-people who can't (or don't want to) run emacs for one
-reason or another, or are not familiar with the
-.Xr vi 1
-editor.
-It is compatible with emacs because there shouldn't
-be any reason to learn more editor types than emacs or
-.Xr vi 1 .
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It + Ns Ar number
-Go to the line specified by number (do not insert
-a space between the
-.Sq +
-sign and the number).
-If a negative number is specified, the line number counts
-backwards from the end of the file i.e. +-1 will be the last
-line of the file, +-2 will be second last, and so on.
-.It Fl f Ar mode
-Run the mode command for all buffers created from
-arguments on the command line, including the
-scratch buffer and all files.
-.It Fl n
-Turn off backup file generation.
-.El
-.Sh WINDOWS AND BUFFERS
-When a file is loaded into
-.Nm ,
-it is stored in a
-.Em buffer .
-This buffer may be displayed on the screen in more than one window.
-At present, windows may only be split horizontally, so each window is
-delineated by a modeline at the bottom.
-If changes are made to a buffer, it will be reflected in all open windows.
-.Pp
-If a buffer name begins and ends with an asterisk, the buffer is considered
-throwaway; i.e. the user will not be prompted to save changes when
-the buffer is killed.
-.Sh POINT AND MARK
-The current cursor location in
-.Nm
-is called the
-.Em point
-(or
-.Em dot ) .
-It is possible to define a window-specific region of text by setting a second
-location, called the
-.Em mark .
-The
-.Em region
-is the text between point and mark inclusive.
-Deleting the character at the mark position leaves
-the mark at the point of deletion.
-.Pp
-Note: The point and mark are window-specific in
-.Nm ,
-not buffer-specific, as in other emacs flavours.
-.Sh BACKUP FILES
-Backup files have a
-.Sq ~
-character appended to the file name and
-are created in the current working directory by default.
-Whether to create backup files or not can be toggled with the
-make-backup-file command.
-The backup file location can either be in the current
-working directory, or all backups can be moved to a
-.Pa ~/.mg.d
-directory where files retain their path name to retain uniqueness.
-Use the backup-to-home-directory to alternate between these two locations.
-Further, if any application creates backup files in the
-.Ev TMPDIR ,
-these can be left with the leave-tmpdir-backups command.
-.Sh TAGS
-.Nm
-supports tag files created by
-.Xr ctags 1 ,
-allowing the user to quickly locate various object definitions.
-Note though that emacs uses etags, not ctags.
-.Sh CSCOPE
-.Nm
-supports navigating source code using cscope.
-However,
-.Nm
-requires cscope and cscope-indexer executables to be present in
-.Ev PATH
-for it to work.
-.Sh DEFAULT KEY BINDINGS
-Normal editing commands are very similar to GNU Emacs.
-In the following examples, C-x means Control-x, and M-x means Meta-x,
-where the Meta key may be either a special key on the keyboard
-or the ALT key; otherwise ESC followed by the key X works as well.

-For a complete description of

-commands, see
-.Sx MG COMMANDS .
-To see the active keybindings at any time, type
-.Dq M-x describe-bindings .
-.Sh MG COMMANDS
-Commands are invoked by
-.Dq M-x ,
-or by binding to a key.
-Many commands take an optional numerical parameter,
-.Va n .
-This parameter is set either by
-M-<n> (where
-.Va n
-is the numerical argument) before the command, or by
-one or more invocations of the universal argument, usually bound to C-u.
-When invoked in this manner, the value of the numeric parameter to
-be passed is displayed in the minibuffer before the M-x.
-One common use of the parameter is in mode toggles (e.g.\&
-make-backup-files).
-If no parameter is supplied, the mode is toggled to its
-alternate state.
-If a positive parameter is supplied, the mode is forced to on.
-Otherwise, it is forced to off.

-If dot is at the end of the line, transpose the two characters before it.
-Return with an error if dot is at the beginning of line;
-it seems to be a bit pointless to
-make this work.
-.It undo
-Undo the most recent action.
-If invoked again without an intervening command,
-move the undo pointer to the previous action and undo it.
-.It undo-boundary
-Add an undo boundary.
-This is not usually done interactively.
-.It undo-boundary-toggle
-Toggle whether undo boundaries are generated.
-Undo boundaries are often disabled before operations that should
-be considered atomically undoable.
-.It undo-enable
-Toggle whether undo information is kept.
-.It undo-list
-Show the undo records for the current buffer in a new buffer.
-.It universal-argument
-Repeat the next command 4 times.
-Usually bound to C-u.
-This command may be stacked; e.g.\&
-C-u C-u C-f moves the cursor forward 16 characters.
-.It upcase-region
-Upper case region.
-Change all of the lower case characters in the region to
-upper case.
-.It upcase-word
-Move the cursor forward by the specified number of words.
-As it moves, convert any characters to upper case.
-.It visit-tags-table
-Record name of the tags file to be used for subsequent find-tag.
-.It what-cursor-position
-Display a bunch of useful information about the current location of
-dot.
-The character under the cursor (in octal), the current line, row,
-and column, and approximate position of the cursor in the file (as a
-percentage) is displayed.
-The column position assumes an infinite
-position display; it does not truncate just because the screen does.
-.It write-file
-Ask for a file name and write the contents of the current buffer to
-that file.
-Update the remembered file name and clear the buffer
-changed flag.
-.It yank
-Yank text from kill-buffer.
-Unlike emacs, the
-.Nm
-kill buffer consists only
-of the most recent kill.
-It is not a ring.
-.El
-.Sh CONFIGURATION FILES
-There are two configuration files,
-.Pa .mg
-and
-.Pa .mg-TERM .
-Here,
-.Ev TERM
-represents the name of the terminal type; e.g. if the terminal type
-is set to
-.Dq vt100 ,
-.Nm
-will use
-.Pa .mg-vt100
-as a startup file.
-The terminal type startup file is used first.
-.Pp
-The startup file format is a list of commands, one per line, as used for
-interactive evaluation.
-Strings that are normally entered by the user at any subsequent prompts
-may be specified after the command name; e.g.:
-.Bd -literal -offset indent
-global-set-key ")" self-insert-command
-global-set-key "\e^x\e^f" find-file
-global-set-key "\ee[Z" backward-char
-set-default-mode fill
-set-fill-column 72
-auto-execute *.c c-mode
-.Ed
-.Sh FILES
-.Bl -tag -width /usr/share/doc/mg/tutorial -compact

-normal startup file
-.It Pa ~/.mg-TERM
-terminal-specific startup file
-.It Pa ~/.mg.d

-.Sh SEE ALSO
-.Xr ctags 1 ,
-.Xr vi 1
-.Sh CAVEATS
-Since it is written completely in C, there is currently no
-language in which extensions can be written;
-however, keys can be rebound and certain parameters can be changed
-in startup files.
-.Pp
-In order to use 8-bit characters (such as German umlauts), the Meta key
-needs to be disabled via the
-.Dq meta-key-mode
-command.
