   3 # Adjust post-install permissions settings.  This rule works off two
   4 # specially-formatted variables, INSTALLPERMS_exec and INSTALLPERMS_data.
   5 # Each is a whitespace-separated list of commands, all of which are either
   6 # a variable assignment or a filename.  Three variables are available:
   7 #
   8 #  - dest= sets the destination directory to e.g., $(sbindir)
   9 #  - chown= controls changes in ownership; value is first argument to chown
  10 #  - chmod= controls changes in permissions; value is first argument to chmod
  11 #
  12 # As a special case, chown=amanda is taken as equivalent to
  13 # chown=$(BINARY_OWNER):$(SETUID_GROUP), which may otherwise have problems with
  14 # whitespace in the user/group names.
  15 #
  16 # when a filename is seen, the currently active variables are applied.
  17 #
  18 # Note that scripts are data, not executables!
  19 #
  20 # EXAMPLE
  21 #
  22 # sbin_PROGRAMS = foo bar bing
  23 # libexec_PROGRAMS = pro gram
  24 # sbin_SCRIPTS = sk ript
  25 # INSTALLPERMS_exec = \
  26 #       dest=$(sbindir) chown=amanda chmod= \
  27 #               foo bar \
  28 #       chmod=u+s,o-rwx \
  29 #               bing
  30 #       dest=$(libexecdir) chmod= \
  31 #               $(libexec_PROGRAMS)
  32 # INSTALLPERMS_data = \
  33 #       dest=$(sbindir) chown=amanda chmod= \
  34 #               $(sbin_SCRIPTS)
  35 #
  36 # This whole operation is not required when making builds for packaging,
  37 # and can be disabled with --disable-installperms, via the WANT_INSTALLPERMS
  38 # AM_CONDITIONAL.
  39

  41 # src/foo/bar.so to bar.so.
