  17 # Installing many files should not exceed the command line length limit.
  18 # Here, the main issue is that we may prepend `$(srcdir)/' to each file,
  19 # which may cause much longer command lines.  The list of files must
  20 # anyway remain below the limit, otherwise `make' won't be able to even
  21 # fork the command.
  22 #
  23 # Further, the install rule should honor failures of the install program.
  24
  25 # Python is done in the sister test.
  26 # For texinfos, we expand names using $(srcdir) in the first place.
