   1 # DIST: This is the distribution Makefile for Emacs.  configure can
   2 # DIST: make most of the changes to this file you might want, so try
   3 # DIST: that first.
   4
   5 # make all      to compile and build Emacs.
   6 # make install  to install it.
   7 # make TAGS     to update tags tables.
   8 #
   9 # make clean  or  make mostlyclean
  10 #      Delete all files from the current directory that are normally
  11 #      created by building the program.  Don't delete the files that
  12 #      record the configuration.  Also preserve files that could be made
  13 #      by building, but normally aren't because the distribution comes
  14 #      with them.
  15 #
  16 #      Delete `.dvi' files here if they are not part of the distribution.
  17 #
  18 # make distclean
  19 #      Delete all files from the current directory that are created by
  20 #      configuring or building the program.  If you have unpacked the
  21 #      source and built the program without creating any other files,
  22 #      `make distclean' should leave only the files that were in the
  23 #      distribution.
  24 #
  25 # make maintainer-clean
  26 #      Delete everything from the current directory that can be
  27 #      reconstructed with this Makefile.  This typically includes
  28 #      everything deleted by distclean, plus more: C source files
  29 #      produced by Bison, tags tables, info files, and so on.
  30 #
  31 # make extraclean
  32 #      Still more severe - delete backup and autosave files, too.

  81 datadir=@datadir@

  83 # Where to install and expect the files that Emacs modifies as it

 429 ###      Like `clean', but may refrain from deleting a few files that people
 430 ###      normally don't want to recompile.  For example, the `mostlyclean'
 431 ###      target for GCC does not delete `libgcc.a', because recompiling it
 432 ###      is rarely necessary and takes a lot of time.

 480 ###      produced by Bison, tags tables, info files, and so on.
 481 ###
 482 ###      One exception, however: `make maintainer-clean' should not delete
 483 ###      `configure' even if `configure' can be remade using a rule in the
 484 ###      Makefile.  More generally, `make maintainer-clean' should not delete
 485 ###      anything that needs to exist in order to run `configure' and then
 486 ###      begin to build the program.

 506 ### Unlocking and relocking.  The idea of these productions is to reduce
 507 ### hassles when installing an incremental tar of Emacs.  Do `make unlock'
 508 ### before unlocking the file to take the write locks off all sources so
 509 ### that tar xvof will overwrite them without fuss.  Then do `make relock'
 510 ### afterward so that VC mode will know which files should be checked in
 511 ### if you want to mung them.
 512 ###
 513 ### Note: it's no disaster if these productions miss a file or two; tar
 514 ### and VC will swiftly let you know if this happens, and it is easily
 515 ### corrected.
