Gantt Chart Display Program For Gabriel,  X11 Version

Programmer: Shuvra Bhattacharrya            

This is the source code for the X11 Gantt chart display library.  It
may be used with either the textual Gabriel interface or the graphical
interface, although as of this writing the textual interface is broken
in the Gabriel end.

If the graphics interface is used, ggirpc links against the libgantt.a
created here.  If the textual interface were to use this, it would
"fasl" against the library.  The Gantt code has a number of function calls
to highlighting routines defined in the ggi code. If the textual
interface calls Gantt, these calls are never executed.  However, dummy
definitions for them must exist to prevent undefined external reference
errors.  The dummy definitions are placed in "textual.c".

A standalone version of the program (for debugging purposes) is included
in the subdirectory "test".  Do a make in the appropriate ~gabriel/obj.$ARCH
directory (e.g., ~gabriel/obj.sun4/src/libgantt/test), and then run "driver",
which takes input from the supplied file "sched.dis".

For debugging, set DEBUG=1 in "displaysched.h".
To select colors for the processors, edit "colors.h".
To select miscellaneous window parameters, edit "displaysched.h".

Save the original parameters before changing them, because
it's possible that some values of certain parameters may cause
problems.
