How to build & install libvte compatible library using mlterm engine.

* Requirements
  o vte library and headers
  o gtk+ 2.x or 3.x
  o terminal emulators or other applications using libvte 
    (gnome-terminal, roxterm, synaptic or etc)

* Build
  $ ./configure (--with-type-engine=cairo --with-imagelib=gdk-pixbuf --enable-pty-helper \
    --with-gtk=2.0 ...)
    (Xft and cairo are not required, but strongly recommended because it is
    impossible to change font settings from preferences menu without them.
    In addition, you should choose what gtk+ and pango installed to your
    system depend on such as gdk-pixbuf.
    If you want to use gnome-pty-helper, specify --enable-pty-helper option and
    place gnome-pty-helper (or its symbolic link file) at ${libexecdir}/mlterm/.
    If libvte on your system depends on gtk+-2.x, specify --with-gtk=2.0 option)
  $ make
  $ cd gtk ; make

* Install (Replace official libvte)
  $ cd kiklib ; make install
  $ cd mkf ; make install
  $ cd gtk ; make install
  $ ln -sf [where libvte of mlterm is installed]/libvte.so.9 \
	   [where official libvte is installed]/libvte.so.9
    or
    ln -sf [where libvte of mlterm is installed]/libvte2_90.so.9 \
	   [where official libvte is installed]/libvte2_90.so.9

* Start terminal emulators using libvte
  $ gnome-terminal (roxterm, synaptic or etc)
  => mlterm inside gnome-terminal is started.

* Notice
  o Because it is mlterm that works inside gnome-terminal or etc,
    - Configuration files in ~/.mlterm/ are applied. (*)
    - Configuration protocol (like '$ mlcc [key] [value]') is mostly available.
    - Pressing Ctrl+Button3 shows 'mlconfig' menu.

    (*) Following configurations are invalidated by gnome-terminal or etc in startup.
       - 'DEFAULT' settings in ~/.mlterm/(v)(aa)font
       - 'bel_mode', 'fg_color', 'bg_color', 'cursor_bg_color', 'wall_picture',
         'use_transbg', 'alpha', 'encoding' and 'blink_cursor' options
	 in ~/.mlterm/main

  o Default value of following options are not same as that of normal mlterm.
    [Option]       [Default Value]                     [Normal mlterm]
    type_engine => xft or cairo (if compiled with it)  (xft)
  
  o Following functions which normal mlterm provides are not available.
    - Daemon mode
    - Multiple ptys using Ctrl+F1 / Ctrl+F2 / Ctrl+F3
    - Vertical writing mode
    - 'screen_width_ratio' and 'screen_height_ratio' options
    - 'inner_border' option
    - 'use_urgent_bell' option

  o It is recommended to specify the same font to configuration of gnome-terminal
    or etc and ~/.mlterm/aafont so as not to load excessive fonts.
    ex) - gtkterm2
    ~/.gtkterm2rc    => terminalFont=Terminal 14
    ~/.mlterm/aafont => DEFAULT=Terminal 14

  o Uim module of mlterm conflicts with the one of gtk+ and segmentation fault
    is caused. (uim 1.5.7)
