# with bootstrap, so set those here where they can still be over-

'environment' show warnings about LIBTOOLIZE_OPTIONS content
'file' show warnings about file copying and linking
The following space or comma delimited options can be passed to $progname
via the environment variable LIBTOOLIZE_OPTIONS, unknown environment
options are ignored:
--debug enable verbose shell tracing
--no-warnings don't display warning messages
--quiet work silently
--verbose verbosely report processing
You must 'cd' to the top directory of your package before you run
'$progname'.
When reporting a bug, please describe a test case to reproduce it and
include the following information:

# used in preference to deriving the default. Call them using their
# associated 'require_*' variable to ensure that they are executed, at
# most, once.
#
# Some of the require functions are very similar, so we generate those
# as this file is sourced. They look complicated, but they are the same
# as normal function declarations wrapped in "eval '<definition>'", so
# that embedded single quotes need to be escaped, and wherever a symbol
# is generated, we drop out of the single quotes and expand a variable
# that holds the symbol.
