## This is a helper script to update the pre-built generated files in
## the autogen/ directory. This is suitable for running from cron.
## Only Emacs maintainers need use this, so it uses bash features.
+##
+## With the -l option, it also updates the versioned loaddefs-like
+## files in lisp/. These include ldefs-boot, cl-loaddefs, rmail, etc.
### Code:
usage ()
{
cat 1>&2 <<EOF
-Usage: ${PN} [-f] [-c] [-q]
+Usage: ${PN} [-f] [-c] [-q] [-l] [-C] [-- make-flags]
Update the generated files in the Emacs autogen/ directory.
Options:
-f: force an update even if the source files are locally modified.
-c: if the update succeeds and the generated files are modified,
commit them (caution).
-q: be quiet; only give error messages, not status messages.
+-l: also update the versioned loaddefs-like files in lisp/.
+This requires a build. Passes any non-option args to make (eg -- -j2).
+-C: start from a clean state. Slower, but more correct.
