+# Q: Do we need to bootstrap?
+# A: Only if we find admin/admin.el, i.e. we are building out of CVS,
+# and src/b-emacs.exe does not exist. This avoids building a
+# bootstrap-emacs and recompiling Lisp files when building a
+# pretest/release tarball.

+# Pass to src/Makefile.in an additional BOOTSTRAPEMACS variable which
+# is either set to b-emacs.exe (in case bootstrap-emacs has not been
+# constructed yet) or the empty string (otherwise).
+# src/Makefile.in uses it to implement conditional dependencies, so that
+# files that need bootstrap-emacs to be built do not additionally need
+# to be kept fresher than b-emacs.exe. Otherwise changing a single
+# file src/foo.c forces dumping a new bootstrap-emacs, then re-byte-compiling
+# all preloaded elisp files, and only then dump the actual src/emacs, which
+# is not wrong, but is overkill in 99.99% of the cases.
