-+ * This driver implements an interface whereby programs such as ps(1), top(1),
-+ * killall(1) and the like may obtain all the process information they need to
-+ * do their jobs.  Now you may ask, "Why not use /proc?  BSD uses /proc.".
-+ * Thanks for asking.  /proc is designed as a virtual filesystem.  As such it
-+ * presents all of its information in a nice, human readable format.  But not
-+ * human readable enough that mere mortals can actually look at the /proc
-+ * information and know what is happening on their computer (which is why we
-+ * have nice programs like ps(1) to help us out.  Additionally, for ps (using
-+ * /proc) to do its job, it has to do something like:
-+ *
-+ *	dir = opendir("/proc");
-+ *	while ((entry = readdir(dir)) != NULL) { 
-+ *		if (!isdigit(*entry->d_name))
-+ *			continue;
-+ *		open_lots_of files();
-+ *		parse_lots_of_strings();
-+ *		close_lots_of_files();
-+ *		print_stuff();
-+ *	}
-+ *
-+ *
-+ * This is bad, because:
-+ *
-+ * 1) opening and closing lots of files is slow,
-+ *
-+ * 2) parsing lots of strings is slow,
-+ *
-+ * 3) every one of those strings had to be carefully printed out and formatted
-+ * by the kernel, which is slow,
-+ *
-+ * 4) using a virtual filesystem is not the traditional UN*X solution to
-+ * getting information from the kernel out to userspace (ioctls and syscalls
-+ * are the established way to do this), and worst of all
-+ *
-+ * 5) having a virtual filesystem around has been so inviting that everyone has
-+ * put their own weird little files into it, causing /proc to become a
-+ * cluttered rubbish heap of 64 flavors of strange that takes a ridiculous
-+ * amount of memory.  
-+ *
-+ * This driver is the first step in my evil plan to completely 
-+ * dismantle /proc.  Muhahahaha!
-+ *
-+ * Suggestions are welcome. Patches that work are more welcome though. ;-)
