23 ### Commentary:
25 ## This is a helper script to update the pre-built generated files in
26 ## the autogen/ directory. This is suitable for running from cron.
27 ## Only Emacs maintainers need use this, so it uses bash features.
29 ## With the -l option, it also updates the versioned loaddefs-like
30 ## files in lisp/. These include ldefs-boot, cl-loaddefs, rmail, etc.
32 ### Code:
34 die () # write error to stderr and exit
36 [ $# -gt 0 ] && echo "$PN: $@" >&2
37 exit 1
40 PN=${0##*/} # basename of script
41 PD=${0%/*}
43 [ "$PD" = "$0" ] && PD=. # if PATH includes PWD
45 ## This should be the autogen directory.
46 cd $PD
47 cd ../
48 [ -d autogen ] || die "Could not locate autogen directory"

54 Usage: ${PN} [-f] [-c] [-q] [-l [-L]] [-C] [-- make-flags]
55 Update the generated files in the Emacs autogen/ directory.
56 Options:
57 -f: force an update even if the source files are locally modified.
58 -c: if the update succeeds and the generated files are modified,
59 commit them (caution).
60 -q: be quiet; only give error messages, not status messages.
61 -l: also update the versioned loaddefs-like files in lisp/.
62 This requires a build. Passes any non-option args to make (eg -- -j2).
63 -L: also update ldefs-boot.el.
64 -C: start from a clean state. Slower, but more correct.
