There is currently no GUI for the OpenSched program.  Hopefully
someone will volunteer for this work.  The GUI would basically
just front-end the configuration file, and perhaps also be
used to run opensched/latex/ghostscript to return PDF reports.

We think that a WWW interface would probably be best for this,
so that non-Linux users could share access to the system.  I 
don't think that fine-grained access controls are needed, but
perhaps someone else might have a requirement for this.

Following are some thoughts about the layout of a GUI for the program.
Presumably doing this with a WWW / HTTP / CGI user interface will be
reasonable.  Maybe the absence of a GUI will bug someone enough 
to write one...  ;-)

  Resource summary


EDIT TASKS:
===========
(print a sorted list of tasks, where tasks are sorted by a weight.
 put a checkbox beside each task.
 
 The weight is calculated based on the depth and number of tasks it
 depends on.  e.g., If A->B means that B depends on A, then the depth of
 C in A->B->C is 3.  If A->B->C and D->C and E->C are true, then C has 1
 level-1 ancestor, and 2 level-2.)
