## Abstract:
## OpenAxiom is built in layers. The first layer is contructed into
## an image called `bootsys'. The `bootsys' image is used
## to translate Boot code to Common Lisp code. Since a Boot coded
## interpreter is needed to translate the code for the Boot coded
## interpreter we have a ``boot-strapping'' problem. In order to get
## the whole process to start we need certain files kept in
## common lisp form. This directory contains those files.
##
## We start with a Lisp image created in a previous build step (src/lisp).
## That image is used to build Boot translator executable through the
## entire bootstrap process.
AXIOM_LOCAL_LISP_sources = initial-env.lisp
AXIOM_LOCAL_LISP = ../lisp/lisp$(EXEEXT)
## FASLs that comprises `bootsys'
boot_SOURCES = initial-env.lisp $(boot_sources)
boot_sources = tokens.boot includer.boot scanner.boot \
pile.boot ast.boot parser.boot translator.boot
boot_clisp = $(boot_sources:.boot=.clisp)
boot_objects = initial-env.$(FASLEXT) $(boot_sources:.boot=.$(FASLEXT))
# Garbage produced by GCL during compilation
boot_data = $(boot_sources:.boot=.data)
boot_fn = $(boot_sources:.boot=.fn)
##
## ECL's program construction model is not based on image-dumping. It is
## closer to `traditional C' application building. Therefore, since
## bootsys is an augmentation of base-lisp, we need to have the objects
## that made up base-lisp too.
