 usage: $0 [--gnulib-srcdir=DIR][--paxutils-srcdir=DIR][--cvs-auth=AUTH-METHOD][--cvs-user=USERNAME][--no-po]
 Options are:
 --paxutils-srcdir=DIRNAME    Specify the local directory where paxutils
                              sources reside. Use this if you already
                              have paxutils sources on your machine, and
                              do not want to waste your bandwidth dowloading
                              them again.
 --gnulib-srcdir=DIRNAME      Specify the local directory where gnulib
                              sources reside. Use this if you already
                              have gnulib sources on your machine, and
                              do not want to waste your bandwidth dowloading
                              them again.
 --cvs-auth=METHOD            Set the CVS access method used for downloading
                              gnulib files. METHOD is one of the keywords
                              accepted by cvs -d option (see info cvs
                              repository).
 --cvs-user=USERNAME          Set the CVS username to be used when accessing
                              the gnulib repository.
 --no-po                      Do not download po files.
 --update-po[=LANG]           Update po file(s) and exit.

If the file \`.bootstrap' exists in the current working directory, its
contents is read, comments and empty lines removed, shell variables expanded
and the result is prepended to the command line options.

Running without arguments will suffice in most cases. It is equivalent
to

    ./bootstrap --cvs-auth=ext --cvs-user=anoncvs
