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.
23 # Further, the install rule should honor failures of the install program.
25 # Python is done in the sister test.
26 # For texinfos, we expand names using $(srcdir) in the first place.
27 # Let's hope nobody uses many texinfos.
