  22 ### Commentary:
  23
  24 # make all      to compile and build Emacs.
  25 # make install  to install it.
  26 # make TAGS     to update tags tables.
  27 #
  28 # make clean  or  make mostlyclean
  29 #      Delete all files from the current directory that are normally
  30 #      created by building the program.  Don't delete the files that
  31 #      record the configuration.  Also preserve files that could be made
  32 #      by building, but normally aren't because the distribution comes
  33 #      with them.
  34 #
  35 #      Delete `.dvi' files here if they are not part of the distribution.
  36 #
  37 # make distclean
  38 #      Delete all files from the current directory that are created by
  39 #      configuring or building the program.  If you have unpacked the
  40 #      source and built the program without creating any other files,
  41 #      `make distclean' should leave only the files that were in the
  42 #      distribution.
  43 #
  44 # make maintainer-clean
  45 #      Delete everything from the current directory that can be
  46 #      reconstructed with this Makefile.  This typically includes
  47 #      everything deleted by distclean, plus more: .elc files,
  48 #      C source files produced by Bison, tags tables, info files,
  49 #      and so on.
  50 #
  51 # make extraclean
  52 #      Still more severe - delete backup and autosave files, too.
  53 #
  54 # make bootstrap
  55 #      Removes all the compiled files to force a new bootstrap from a
  56 #      clean slate, and then build in the normal way.
  57 #
  58 # make docs
  59 #      Make Emacs documentation files from their sources; requires makeinfo.

 487 ## We delete each directory in ${COPYDESTS} before we copy into it;

 494 ## other builds in the source directory.  This is ok because we just
 495 ## deleted the entire installed etc/ directory and recreated it.

 501 ## I'm not sure creating locallisppath here serves any useful purpose.
 502 ## If it has the default value, then the later write_subdir commands

 504 ## This will only do something if locallisppath has a non-standard value.
 505 ## Is it really Emacs's job to create those directories?
 506 ## Should we also be ensuring they contain subdirs.el files?
 507 ## It would be easy to do, just use write_subdir.
