Monica is a monitor calibration tool using the FLTK library.
 It works as frontend to xgamma to alter the gamma correction
 for XFree86 or Xorg. The black point, gray and color blocks 
 help to find usable settings for a target of 2.2 gamma, the 
 Web and sRGB standard. FLTK libs are NOT needed for binary. 
 License is BSD revised (without the advertising BS of the 
 original.)

 The grey box with lines illustrates a display gamma of 2.2,
 the sRGB standard gamma.The image is part of one by Norman Koren,
 who has a very helpful website regarding monitor calibration at:

 HOW TO
 1.) If possible, with the monitor controls, set the white point to 6,500K.
 2.) Again on the monitor, increase your contrast to 100%
 3.) And lastly on your monitor, raise the brightness until a
      grey space is BARELY discernable in the black square.
 4.) Using the grey 2.2 gamma image for reference, adjust
      Monica's color sliders to create an even grey.
 5.) If the grey has a color cast to it, then uncheck
      "Synchronize Colors" and adjust colors individually.

 In rare cases xgamma/Monica may not work with some graphic devices.
 Monica stores the gamma correction values in:     $HOME/.monicarc
 and adds the call for .monicarc on system startup to: 
 $HOME/.xinitrc -- or for graphical logons, the user bash startup file:
 ($HOME/.bash_profile or  $HOME/.bash_login or $HOME/.profile)

 If monica cannot locate one of the startup files listed above,
 you may have to place the call to monicarc manually.
 Or place the values into your x-config file (in the MONITOR section)
 in the format of: Gamma 1.05 1.15 1.136

 To compile from source code, you will need the fltk libs.
