6 ;;;; This software is derived from the CMU CL system, which was

12 ;;; This is a linear ordering of system sources which works both to
13 ;;; compile/load the cross-compiler under the host Common Lisp and to
14 ;;; cross-compile the compiler into the under-construction target
17 ;;; Of course, it'd be very nice to have this be a dependency DAG
18 ;;; instead, so that we could do automated incremental recompilation.
19 ;;; But the dependencies are varied and subtle, and it'd be extremely
20 ;;; difficult to extract them automatically, and it'd be extremely
21 ;;; tedious and error-prone to extract them manually, so we don't
22 ;;; extract them. (It would be nice to fix this someday. The most
23 ;;; feasible approach that I can think of would be to make the
24 ;;; dependencies work on a package level, not an individual file
25 ;;; level. Doing it at the package level would make the granularity
26 ;;; coarse enough that it would probably be pretty easy to maintain
27 ;;; the dependency information manually, and the brittleness of the
28 ;;; package system would help make most violations of the declared
29 ;;; dependencies obvious at build time. -- WHN 20000803
