The canonical version of this 23# script is maintained as build-aux/bootstrap in gnulib, however, to 24# be useful to your project, you should place a copy of it under 25# version control in the top-level directory of your project. The 26# intent is that all customization can be done with a bootstrap.conf 27# file also maintained in your version control; gnulib comes with a 28# template build-aux/bootstrap.conf to get you started. 29 30# Please report bugs or propose patches to bug-gnulib@gnu.org. 31 32nl=' 33' 34 35# Ensure file names are sorted consistently across platforms. 36LC_ALL=C 37export LC_ALL 38 39local_gl_dir=gl 40 41me=$0 42 43usage() { 44 cat <<EOF 45Usage: $me [OPTION]... 46Bootstrap this package from the checked-out sources. 47 48Options: 49 --gnulib-srcdir=DIRNAME specify the local directory where gnulib 50 sources reside.
