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.

49 Bootstrap this package from the checked-out sources.
50
51 Options:
52 --gnulib-srcdir=DIRNAME Specify the local directory where gnulib
53 sources reside. Use this if you already
54 have gnulib sources on your machine, and
55 do not want to waste your bandwidth downloading
56 them again. Defaults to \$GNULIB_SRCDIR.
57 --bootstrap-sync If this bootstrap script is not identical to
58 the version in the local gnulib sources,
59 update this script, and then restart it with
60 /bin/sh or the shell \$CONFIG_SHELL if
61 defined.
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 --skip-po Do not download po files.
67
68 If the file $0.conf exists in the same directory as this script, its
69 contents are read as shell variables to configure the bootstrap.
70
71 For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
72 are honored.
73
74 Running without arguments will suffice in most cases.
