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 39# Ensure that CDPATH is not set.

If \$GNULIB_SRCDIR is set (directly or via 88 --gnulib-srcdir) and is a git repository, then it is used as a reference. 89 90 * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir), 91 then sources are fetched from that local directory. If it is a git 92 repository and \$GNULIB_REVISION is set, then that revision is checked 93 out. 94 95 * Otherwise, if this package is in a git repository with a 'gnulib' 96 submodule configured, then that submodule is initialized and updated and 97 sources are fetched from there. 98 99 * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are 100 cloned into that directory using git from \$GNULIB_URL, defaulting to 101 $default_gnulib_url. 102 If \$GNULIB_REVISION is set, then that revision is checked out. 103 104 * Otherwise, the existing Gnulib sources in the 'gnulib' directory are 105 used. If it is a git repository and \$GNULIB_REVISION is set, then that 106 revision is checked out. 107 108If you maintain a package and want to pin a particular revision of the 109Gnulib sources that has been tested with your package, then there are two 110possible approaches: either configure a 'gnulib' submodule with the 111appropriate revision, or set \$GNULIB_REVISION (and if necessary 112\$GNULIB_URL) in $me.conf. 113 114Running without arguments will suffice in most cases. 115EOF 116} 117 118copyright_year=`echo "$scriptversion" | sed -e 's/[^0-9].*//'` 119copyright="Copyright (C) ${copyright_year} Free Software Foundation, Inc. 120License GPLv3+: GNU GPL version 3 or later <https://gnu.org/licenses/gpl.html>. 121This is free software: you are free to change and redistribute it. 122There is NO WARRANTY, to the extent permitted by law." 123 124# warnf_ FORMAT-STRING ARG1... 125warnf_ () 126{ 127 warnf_format_=$1 128 shift 129 nl=' 130' 131 case $* in 132 *$nl*) me_=$(printf "$me"|tr "$nl|" '??') 133 printf "$warnf_format_" "$@" | sed "s|^|$me_: |" ;; 134 *) printf "$me: $warnf_format_" "$@" ;; 135 esac >&2 136} 137 138# warn_ WORD1... 139warn_ () 140{ 141 # If IFS does not start with ' ', set it and emit the warning in a subshell. 142 case $IFS in 143 ' '*) warnf_ '%s\n' "$*";; 144 *) (IFS=' '; warn_ "$@");; 145 esac 146} 147 148# die WORD1... 149die() { warn_ "$@"; exit 1; } 150 151# Configuration. 152 153# Name of the Makefile.am 154gnulib_mk=gnulib.mk 155 156# List of gnulib modules needed. 157gnulib_modules= 158 159# Any gnulib files needed that are not in modules. 160gnulib_files= 161 162: ${AUTOPOINT=autopoint} 163: ${AUTORECONF=autoreconf} 164 165# A function to be called for each unrecognized option.
