  20 # make all      to compile and build Emacs.
  21 # make install  to install it (installs in-place, in `bin' subdir of top dir).
  22 # make TAGS     to update tags tables.
  23 #
  24 # make clean  or  make mostlyclean
  25 #      Delete all files from the current directory that are normally
  26 #      created by building the program.  Don't delete the files that
  27 #      record the configuration.  Also preserve files that could be made
  28 #      by building, but normally aren't because the distribution comes
  29 #      with them.
  30 #
  31 #      Delete `.dvi' files here if they are not part of the distribution.
  32 #
  33 # make distclean
  34 #      Delete all files from the current directory that are created by
  35 #      configuring or building the program.  If you have unpacked the
  36 #      source and built the program without creating any other files,
  37 #      `make distclean' should leave only the files that were in the
  38 #      distribution.
  39 #
  40 # make maintainer-clean
  41 #      Delete everything from the current directory that can be
  42 #      reconstructed with this Makefile.  This typically includes
  43 #      everything deleted by distclean, plus more: *.elc files,
  44 #      C source files produced by Bison, tags tables, info files,
  45 #      and so on.
  46 #
  47 # make extraclean
  48 #      Still more severe - delete backup and autosave files, too.
  49
  50 # This gork is required for those who use a Unix-style shell, and
  51 # have SHELL in the environment pointing to it.  Here we force
  52 # Make to use COMMAND.COM instead.  This Makefile won't work otherwise.
  53 # (The /xyzzy directory is used to minimize the chance that someone
  54 # actually has such a directory with an incompatible command.com.  We
  55 # used to have /dos there, but some Windows installations have an old
  56 # version of DOS stashed in that directory, and command.com from there
  57 # won't run on Windows, complaining about "Incorrect DOS version".
  58 # Make will look up PATH for the shell executable, so the directory name
  59 # is not important.)

  69 # Q: Do we need to bootstrap?
  70 # A: Only if we find admin/admin.el, i.e. we are building out of
  71 #    a VCS-checkout (not a release) and src/b-emacs.exe does not exist.
  72 #    This avoids building a bootstrap-emacs and recompiling Lisp files
  73 #    when building a pretest/release tarball.
