-A STATEMENT ON LEGACY SUPPORT
-
-In the terminal world there is much cruft that comes from old and unsup‐
-ported terminals that inherit incompatible modes and escape sequences
-which noone is able to know, except when he/she comes from that time and
-developed a graphical vt100 emulator at that time.
-
-One goal of st is to only support what is really needed. When you en‐
-counter a sequence which you really need, implement it. But while you
-are at it, do not add the other cruft you might encounter while sneek‐
-ing at other terminal emulators. History has bloated them and there is
-no real evidence that most of the sequences are used today.

-.SH DESCRIPTION
-.B st
-is a simple terminal emulator.
-.SH OPTIONS
-.TP
-.B \-a
-disable alternate screens in terminal
-.TP
-.BI \-c " class"
-defines the window class (default $TERM).
-.TP
-.BI \-f " font"
-defines the
-.I font
-to use when st is run.
-.TP
-.BI \-g " geometry"
-defines the X11 geometry string.
-The form is [=][<cols>{xX}<rows>][{+-}<xoffset>{+-}<yoffset>]. See
-.BR XParseGeometry (3)
-for further details.
-.TP
-.B \-i
-will fixate the position given with the -g option.
-.TP
-.BI \-n " name"
-defines the window instance name (default $TERM).
-.TP
-.BI \-o " iofile"
-writes all the I/O to
-.I iofile.
-This feature is useful when recording st sessions. A value of "-" means
-standard output.
-.TP
-.BI \-T " title"
-defines the window title (default 'st').
-.TP
-.BI \-t " title"
-defines the window title (default 'st').
-.TP
-.BI \-w " windowid"
-embeds st within the window identified by
-.I windowid
-.TP
-.BI \-l " line"
-use a tty
-.I line
-instead of a pseudo terminal.
-.I line
-should be a (pseudo-)serial device (e.g. /dev/ttyS0 on Linux for serial port
-0).
-When this flag is given
-remaining arguments are used as flags for
-.BR stty(1).
-By default st initializes the serial line to 8 bits, no parity, 1 stop bit
-and a 38400 baud rate. The speed is set by appending it as last argument
-(e.g. 'st -l /dev/ttyS0 115200'). Arguments before the last one are
-.BR stty(1)
-flags. If you want to set odd parity on 115200 baud use for example 'st -l
-/dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for
-example 'st -l /dev/ttyS0 cs7 115200'. See
-.BR stty(1)
-for more arguments and cases.
-.TP
-.B \-v
-prints version information to stderr, then exits.
-.TP
-.BI \-e " command " [ " arguments " "... ]"
-st executes
-.I command
-instead of the shell. If this is used it
-.B must be the last option
-on the command line, as in xterm / rxvt.
-This option is only intended for compability,
-and all the remaining arguments are used as a command
-even without it.
-.SH SHORTCUTS
-.TP
-.B Break
-Send a break in the serial line.
-Break key is obtained in PC keyboards
-pressing at the same time control and pause.
-.TP
-.B Ctrl-Print Screen
-Toggle if st should print to the
-.I iofile.
-.TP
-.B Shift-Print Screen
-Print the full screen to the
-.I iofile.
-.TP
-.B Print Screen
-Print the selection to the
-.I iofile.
-.TP
-.B Alt-Shift-Page Up
-Increase font size.
-.TP
-.B Alt-Shift-Page Down
-Decrease font size.
-.TP
-.B Alt-Shift-Home
-Reset to default font size.
-.TP
-.B Shift-Insert
-Paste from primary selection (middle mouse button).
-.TP
-.B Alt-Shift-Insert
-Paste from clipboard selection.
-.TP
-.B Alt-Shift-c
-Copy the selected text to the clipboard selection.
-.TP
-.B Alt-Shift-v
-Paste from the clipboard selection.
-.TP
-.B Alt-Ctrl
-Launch dmenu to enter a unicode codepoint and send the corresponding glyph
-to st.
-.SH CUSTOMIZATION
-.B st
-can be customized by creating a custom config.h and (re)compiling the source
-code. This keeps it fast, secure and simple.
