      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.

if ! FORBID_DOWNLOAD

config FORCE_DOWNLOAD

    bool

    prompt "Force downloads"

    default n

    help

      Force downloading tarballs, even if one already exists.

      Usefull if you suspect a tarball to be damaged.

menuconfig USE_MIRROR

    bool

    prompt "Use LAN mirror"

    default n

    help

      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.

if USE_MIRROR

config PREFER_MIRROR

    bool

    prompt "Prefer the mirror"

    default n

    help

      Say 'Y' here if you prefer the LAN miror over the upstream sources.

config MIRROR_BASE_URL

    string

    prompt "Base URL"

    default "http://ymorin.is-a-geek.org/mirrors/"

    help

      This is the base URL searched in for tarballs.

      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... Also, no guarantee is made as to its

      availability. Use at your own risks.

      The mirror is available at:

        http://ymorin.is-a-geek.org/mirrors/

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.

config DOWNLOAD_MAX_CHUNKS

    int

    prompt "Maximum number of // chunks"

    default 5

    range 1 10

    help

      If you have aria2 installed, then it will be used to download files.

      Aria2 can split the download in chunks, and download those chunks in //

      which can be interesting to speed up the download.

      On the other hand, using many chunks, or even chunking in general, may

      be seen by some site admins as being kind of unfair, or even as a DoS.

      That's why the range of acceptable values is [1..10], and the default

      is 5 (aria2's default).

config ONLY_DOWNLOAD

    bool

    prompt "Stop after downloading tarballs"

    default n

    help

      Only download the tarballs. Exit once it done.

      Usefull to pre-retrieve the tarballs before going off-line.
