Ok.  Here's that alternative, more reasonably implemented, and *tested*
this time :-) (at least as far as reading files, sorting them, and
executing scripts is concerned).  The dependence-extraction mechanism
still needs to be verified, though.  Comments and suggestions for
improvement are welcome.

==============================================================================
ChangeLog:
2003-03-03  Igor Pechtchanski <pechtcha at cs dot nyu dot edu>

	* postinstall.cc (RunFindVisitor::executeAll): New
	member function that propagates script dependencies,
	topologically sorts the script list, and then executes
	the scripts (via other calls).
	(RunFindVisitor::visitFile): Change to add script to
	list instead of running it immediately.
	(RunFindVisitor::files): New member variable.
	(RunFindVisitor::checkAndLogMissingDependencies): New
	member function.
	(FileDesc): New class that extracts and stores
	dependencies from a script file.
	(DEPEND_STR): New #define.
	(do_postinstall): Add executeAll() call.
