22 # Originally written by Paul Eggert. 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.
30 # Please report bugs or propose patches to bug-gnulib@gnu.org.
35 # Ensure file names are sorted consistently across platforms.
41 # Temporary directory names.

49 Usage: $me [OPTION]...
50 Bootstrap this package from the checked-out sources.
53 --gnulib-srcdir=DIRNAME specify the local directory where gnulib
54 sources reside. Use this if you already
55 have gnulib sources on your machine, and
56 do not want to waste your bandwidth downloading
57 them again. Defaults to \$GNULIB_SRCDIR
58 --bootstrap-sync if this bootstrap script is not identical to
59 the version in the local gnulib sources,
60 update this script, and then restart it with
61 /bin/sh or the shell \$CONFIG_SHELL
62 --no-bootstrap-sync do not check whether bootstrap is out of sync
63 --copy copy files instead of creating symbolic links
64 --force attempt to bootstrap even if the sources seem
65 not to have been checked out
66 --no-git do not use git to update gnulib. Requires that
67 --gnulib-srcdir point to a correct gnulib snapshot
68 --skip-po do not download po files
70 If the file $me.conf exists in the same directory as this script, its
71 contents are read as shell variables to configure the bootstrap.
73 For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
76 Running without arguments will suffice in most cases.
