       Not all ANSI terminal features are emulated.  If you experience rendering  issues,  you  can  export  the
       environment  variable  TCVT_DEVEL.   It  causes  tcvt  to  crash  upon  seeing an unimplemented character
       sequence.  The error message includes the unrecognized sequence.

       The  two  column  virtual  terminal  emulates  a  virtual  terminal inside another virtual terminal.  The
       emulated virtual terminal is twice as tall and half as wide as the original terminal.  The upper half  of
       the  virtual terminal goes to the left and the lower half goes to the right of the original terminal.  An
       ANSI terminal is emulated.

       While tcvt does this conversion unconditionally, the optcvt can be used with smaller terminals.  It  will
       only invoke tcvt, if the terminal is wide enough and otherwise simply exec the passed program.

       The  exit  status  of  the wrapped program is propagated.  When tcvt produces an error of its own, 255 is
       returned.

       Both programs take a program and options to that program.  They execute the given program.  If no program
       is given a shell is executed.

       In addition the tcvt tool accepts a few switches.

       -c, --columns
               Specify the number of columns. This defaults to two.

       -h, --help
               Print a quick option overview and exit.

       -r, --reverse
               Order columns so that the last one is the left most.

       --      Signal end of options.

       Any non-option argument signals the end of options for tcvt.
