  22 # make all      to compile and build Emacs.
  23 # make install  to install it.
  24 # make TAGS     to update tags tables.
  25 #
  26 # make clean  or  make mostlyclean
  27 #      Delete all files from the current directory that are normally
  28 #      created by building the program.  Don't delete the files that
  29 #      record the configuration.  Also preserve files that could be made
  30 #      by building, but normally aren't because the distribution comes
  31 #      with them.
  32 #
  33 #      Delete '.dvi' files here if they are not part of the distribution.
  34 #
  35 # make distclean
  36 #      Delete all files from the current directory that are created by
  37 #      configuring or building the program.  If you have unpacked the
  38 #      source and built the program without creating any other files,
  39 #      'make distclean' should leave only the files that were in the
  40 #      distribution.
  41 #
  42 # make maintainer-clean
  43 #      Delete everything from the current directory that can be
  44 #      reconstructed with this Makefile.  This typically includes
  45 #      everything deleted by distclean, plus more: .elc files,
  46 #      C source files produced by Bison, tags tables, info files,
  47 #      and so on.
  48 #
  49 # make extraclean
  50 #      Still more severe - delete backup and autosave files, too.
  51 #      Also generated files that do not normally change and can be slow
  52 #      to rebuild (eg leim/ja-dic).
  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.
  60 #
  61 # make check (or check-expensive or check-all)
  62 #      Run the Emacs test suite.
  63 #      check-expensive includes additional tests that can be slow.
  64 #      check-all runs all tests, including ones that can be slow, or
  65 #        fail unpredictably

 543 ## It would be simpler to have a separate install rule for etc/refcards
 544 ## (maybe move it to doc/refcards?).
 545
 546 ## Note that the Makefiles in the etc directory are potentially useful
 547 ## in an installed Emacs, so should not be excluded.
 548
 549 ## We always create the _default_ locallisppath directories, and
 550 ## ensure that they contain a subdirs.el file (via write_subdir).
 551 ## This is true even if locallisppath has a non-default value.
 552 ## In case of non-default value, we used to create the specified directories,
 553 ## but not add subdirs.el to them.  This was a strange halfway house.
 554 ## Nowadays we do not create non-default directories.
 555
