This is the RTEMS Graphics Toolkit. It is a collection of free software
packages that are suitable for use in building graphical interfaces for
RTEMS-based embedded systems.

You should have RTEMS installed and configured for your BSP.  The
RTEMS configuration should meet the following requirements:

+ TCP/IP enabled 
  - not required at run-time but has endian swapping routines
+ POSIX enabled

Additionally, your BSP should have a framebuffer and pointing device
(e.g. mouse, touch screen, etc).  This is an area where RTEMS and
this kit needs improvement on configuration but the basics are in place.

The ./do_it script has the following parameters:

    do_one [options]
      -A - build and install all libraries
      -j - build JPEG support (default=no)
      -p - build PNG support (default=no)
      -t - build TIFF support (default=no)
      -1 - build Adobe Type 1 font support (default=no)
      -T - build Truetype font support (default=no)
      -c - clean after building (default=no)
      -v - verbose

    NOTES:
      + Use of each option toggles the setting.  For example, \"-v -v -A -1\"
        results in verbose=no and all steps done except Type 1 fonts.
      + RTEMS_MAKEFILE_PATH must be set
      + By default, nothing is built.

Below is an invocation for the pc386 BSP which should build all of the
supported libraries and install them for the pc386 BSP which is installed
into your ${HOME}.  RTEMS was configured with --prefix set to:
${HOME}/rtems-4.10-work/bsp-install/

RTEMS_MAKEFILE_PATH=${HOME}/rtems-4.10-work/bsp-install/i386-rtems4.10/pc386/ \
    ./do_it -A -v

The CFLAGS and target information are automatically gathered from the
install Makefile information.  This is used to properly configure
and install the desired graphics support libraries.

After installing this, you can proceed to building Microwin/Nano-X.  It
is expected that this will be integrated into a future revision of the
Graphics Toolkit.  We hope to add other libraries like SVGAlib and
FLTK in the future.  This is definitely an area in which users can 
contribute.

Usage Notes:

Adobe Type 1 Library
====================
+ This needs .t1librc and an override on the location of t1 fonts.
  Then we need to put some T1 fonts in the rootfs filesystem.
  This works now by setting the environment variable.  See rtems_init.c
  in the microwin source.
