+# You probably don't want to be using this script unless you

+#
+# This script is not a reliable way to build the system, but it is
+# fast.:-| It can be useful if you are trying to debug a low-level
+# problem, e.g. a problem in src/runtime/*.c or in
+# src/code/cold-init.lisp. Soon, you'll find yourself wanting to
+# test a small change in a file compiled into cold-sbcl.core without
+# redoing the entire rebuild-the-system-from-scratch process. You may be
+# able to avoid a complete make-host-2.sh by just letting this script
+# rebuild only files that have changed. On the other hand, it might
+# not work...
+#
+# It's not anywhere rigorously correct for all small changes, much
+# less for all large changes. It can't be, unless we either solve the
+# halting problem or totally rearchitect the SBCL sources to support
+# incremental recompilation. Beyond that fundamental limitation, even
+# an easy special case might not work unless someone's paid attention
+# to making it work. Here are some highlights to help you understand
+# when it will work:
+# * It will rebuild a .fasl file when the corresponding
+# .lisp file is out of date.
+# * It rebuilds the src/runtime/ files completely, since that
+# doesn't take very long anyway.
+# * Apparently it will not rebuild assembly-code-in-.lisp files
+# even when the sources are out of date. This is probably not a
+# fundamental limitation, it's just that I (WHN 2002-01-16)
+# have made vanishingly nontrivial changes to assembler files,
+# so I'm not motivated. If you're motivated, please send a patch.
+# * It will not notice when you change something in one .lisp file
+# which should affect the compilation of code in another .lisp
+# file. E.g.
+# ** changing the definition of a macro used in another file (or a
+# function or a variable which is used at macroexpansion time)
+# ** changing the value of a DEFCONSTANT used in another file
+# ** changing the layout of a structure used in another file
+# ** changing the PROCLAIMed type of something used in another
+# file
+# Mostly it looks as though such limitations aren't fixable without
+# the aforementioned rearchitecting or solving the halting problem.
+#
+# To make this work, you need an after-xc.core file. To cause the
+# system to generate an after-xc.core file, you need
+# :SB-AFTER-XC-CORE in target features during an ordinary build.
+# See the comments in base-target-features.lisp-expr for the
+# recommended way to make that happen.
