# Regenerate auto-generated files (e.g. configure)
#
# If the -s option is given, save the autogenerated scripts in
# $SAGE_ROOT/upstream/configure-$CONFVERSION.tar.gz where CONFVERSION
# is the sha1 of HEAD `git rev-parse HEAD`
#
# If optional argument -d is given and bootstrapping failed, instead
# extract the files from a local configure tarball, downloading it if
# needed. If -D is given, don't try to bootstrap and always extract or
# download.
#
# If optional argument -u <URL> is given download the configure
# tarball from that base url. That is, "bootstrap -u http://host/path"
# will download http://host/path/configure-$CONFVERSION.tar.gz to
# upstream/configure-$CONFVERSION.tar.gz. This is used by the buildbot
# to download tarballs that are not published.
#
# The -q (quiet) flag hides all "informational" output.
