# Installing many files should not exceed the command line length limit.
|
|
# Here, the main issue is that we may prepend '$(srcdir)/' to each file,
|
|
# which may cause much longer command lines. The list of files must
|
|
# anyway remain below the limit, otherwise 'make' won't be able to even
|
|
# fork the command.
|
|
#
|
|
# Further, the install rule should honor failures of the install program.
|
|
|
|
# Python is done in the sister test.
|
|
# For texinfos, we expand names using $(srcdir) in the first place.
|
|
# Let's hope nobody uses many texinfos.
