39 Bootstrap this package from the checked-out sources.
42 --gnulib-srcdir=DIRNAME Specify the local directory where gnulib
43 sources reside. Use this if you already
44 have gnulib sources on your machine, and
45 do not want to waste your bandwidth downloading
47 --copy Copy files instead of creating symbolic links.
48 --force Attempt to bootstrap even if the sources seem
49 not to have been checked out.
50 --skip-po Do not download po files.
52 If the file $0.conf exists in the same directory as this script, its
53 contents are read as shell variables to configure the bootstrap.
55 For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
58 Running without arguments will suffice in most cases.
