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.

54 Usage: $me [OPTION]...
55 Bootstrap this package from the checked-out sources.
57 Options:
58 --gnulib-srcdir=DIRNAME specify the local directory where gnulib
59 sources reside. Use this if you already
60 have gnulib sources on your machine, and
61 do not want to waste your bandwidth downloading
62 them again. Defaults to \$GNULIB_SRCDIR
63 --bootstrap-sync if this bootstrap script is not identical to
64 the version in the local gnulib sources,
65 update this script, and then restart it with
66 /bin/sh or the shell \$CONFIG_SHELL
67 --no-bootstrap-sync do not check whether bootstrap is out of sync
68 --copy copy files instead of creating symbolic links
69 --force attempt to bootstrap even if the sources seem
70 not to have been checked out
71 --no-git do not use git to update gnulib. Requires that
72 --gnulib-srcdir point to a correct gnulib snapshot
73 --skip-po do not download po files
75 If the file $me.conf exists in the same directory as this script, its
76 contents are read as shell variables to configure the bootstrap.
78 For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
79 are honored.
81 Gnulib sources can be fetched in various ways:
83 * If this package is in a git repository with a 'gnulib' submodule
84 configured, then that submodule is initialized and updated and sources
85 are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
86 --gnulib-srcdir) and is a git repository, then it is used as a reference.
88 * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
89 then sources are fetched from that local directory. If it is a git
90 repository and \$GNULIB_REVISION is set, then that revision is checked
91 out.
93 * Otherwise, if this package is in a git repository with a 'gnulib'
94 submodule configured, then that submodule is initialized and updated and
95 sources are fetched from there.
97 * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
98 cloned into that directory using git from \$GNULIB_URL, defaulting to
99 $default_gnulib_url.
100 If \$GNULIB_REVISION is set, then that revision is checked out.
102 * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
103 used. If it is a git repository and \$GNULIB_REVISION is set, then that
104 revision is checked out.
106 If you maintain a package and want to pin a particular revision of the
107 Gnulib sources that has been tested with your package, then there are two
108 possible approaches: either configure a 'gnulib' submodule with the
109 appropriate revision, or set \$GNULIB_REVISION (and if necessary
110 \$GNULIB_URL) in $me.conf.
112 Running without arguments will suffice in most cases.
