The run time library is spread across a bunch of assembly
source code files.  This is to keep them all in separate program
hunks, which as far as I know cannot be done just through assembler
tricks.  If there is a way, I'd sure love to hear about it.
	In any case, the system is fairly simple.  You use the
script files 'makesystem' or 'makewriters', etc., to create small
sub-libraries, if you will, of related routines.  These are then
joined together with 'makepcqlib', which creates the library.
	If you need to change one routine, just assemble it.  Then
create the sub-library that the module belongs to.  Then re-create
the entire library.  Of course, in order for this to work you'll
need to have object code versions of all the library files in this
directory.  Just assemble them all.
	It is only recently that I came across an object module
librarian (who would think to look on the very early disks?).  I
haven't tried it out yet, but it should make this process a bit
easier.
