      Normally, crosstool-NG will try to download missing tarballs (or
      checkout from CVS/SVN...).
      If you do not have network connectivity when you run crosstool-NG,
      and some files are missing, it can be a long time before crosstool-NG
      fails.
      
      Saying 'y' here will prevent crosstool-NG from downloading missing
      files, thus failing early so that you don't get stuck.

      Force downloading tarballs, even if one already exists.
      
      Usefull if you suspect a tarball to be damaged.

      Say 'Y' here if you need to use a proxy to connect to the internet.
      
      You can then choose between an HTTP or a SOCKS 4/5 proxy.
      
      **** NOTE ****
      The settings below may not cover all possible proxy configurations!
      You'd be better off setting proxy in the environment!

    help
      Use an HTTP proxy to connect to to the internet.
      Only the http and ftp protocols will be tunneled through this
      proxy.
      
      Alternatively to setting this option, you can set and export the
      following variables in your environment:
        ftp_proxy=http://user:passwd@proxy.server:port/
        http_proxy=http://user:passwd@proxy.server:port/

      Use a Socks 4/5 proxy to connect to the internet.
      All protocols can get tunneled through this kind of proxy (your
      proxy configuration may not allow all protocols, but chances are
      that protocols needed by crosstool-NG are allowed).
      
      Alternatively to setting this option, you can configure tsocks
      system-wide, and set and export the following variable in your
      environment:
        LD_PRELOAD=/path/to/your/tsocks-library.so
      
      This option makes use of the tsocks library. You will have to have tsocks
      installed on your system, of course.
      
      If you think you do not know what tsocks is, or how to configure it,
      chances are that you do not need to set this option.

      If you have a machine on your LAN that mirrors some of the needed
      tarballs, you can say 'Y' here, and configure adequate values in
      the following options.
      
      Tarballs will be be preferably fetched from the LAN mirror, and if
      not found there, standard places will be searched for.
      
      Obviously, nothing prevents you from using a mirror that is in fact
      *not* on your LAN, for example on another subnet of your company's
      network, or a mirror on the Internet.
      
      I (Yann E. MORIN) have set up such a mirror to host snapshots of
      some components, when those snapshots are volatile on the upstream
      servers. The mirror is *slow*, because it is hosted behind an ADSL
      line. For the time being, I haven't set up bandwidth limitations,
      but should the mirror be abused, I will. Please avoid using my
      machine when you can...
      The mirror is available as (fill in those values in the fields
      below):
        host name: ymorin.is-a-geek.org
        base dir : /mirrors

    default ""
    help
      This is the base directory searched for for tarballs. If you enter
      /mirror, then the search is performed in the following directories
      on the server:
        /mirror/<name>/
        /mirror/
      
      where <name> is replaced with the actual package name.

      If the tarball was not found at the above location, see if the server
      has a ls-lr.gz (or similar) file, and use that file to see if the
      tarball is listed somewhere in that file.
      
      Common file names looked for are:
        ls-lrRt.txt     (used at ftp.gnu.org)
        find.txt        (ditto)
        ls-lR

config CONNECT_TIMEOUT
    int
    prompt "connection timeout"
    default 10
    help
      From the curl manual:
        Maximum time in seconds that you allow the connection to the server to take.
      
      The scenario is as follows;
        - some enterprise networks have firewalls that prohibit FTP traffic, while
          still allowing HTTP
        - most download sites have http:// equivalent for the ftp:// URL
        - after this number of seconds, it is considered that the connection could
          not be established, and the next URL in the list is tried, until we reach
          an URL that will go through the firewall, most probably an http:// URL.
      
      If you have a slow network, you'd better set this value higher than the default
      10s. If you know a firewall is blocking connections, but your network is globally
      fast, you can try to lower this value to jump more quickly to allowed URLs. YMMV.
      
      Note that this value applies equally to wget if you have that installed.
      
      Of course, you'd be better off to use a proxy, as offered by the previous
      option.

config ONLY_DOWNLOAD
