# acoutput-fast.pl - Quickly create makefiles that are in a common format.
|
|
|
|
#
|
|
|
|
# Most of the makefiles in mozilla only refer to two configure variables:
|
|
|
|
# @srcdir@
|
|
|
|
# @top_srcdir@
|
|
|
|
# However, configure does not know any better and it runs sed on each file
|
|
|
|
# with over 150 replacement rules (slow as molasses).
|
|
|
|
#
|
|
|
|
# This script takes a list of makefiles as input. For example,
|
|
|
|
#
|
|
|
|
# echo $MAKEFILES | acoutput-fast.pl
|
|
|
|
#
|
|
|
|
# The script creates each Makefile that only references @srcdir@ and
|
|
|
|
# @top_srcdir@. For other files, it lists them in a shell command that is
|
|
|
|
# printed to stdout:
|
|
|
|
#
|
|
|
|
# CONFIG_FILES="unhandled_files..."; export CONFIG_FILES
|
|
|
|
#
|
|
|
|
# This command can be used to have config.status create the unhandled
|
|
|
|
# files. For example,
|
|
|
|
#
|
|
|
|
# eval "echo $MAKEFILES | acoutput-fast.pl"
|
|
|
|
# AC_OUTPUT($MAKEFILES)
|
