manual network setup, manage multiple wifi access

[Mihamina Rakotomandimby]

Hi all,

I would like to manually setup my network on my laptop, not with 
NetworkManager.

I am especially looking for a way to manage Wifi network.

Just for example, on Debian/Ubuntu, I use:

  # /etc/network/interfaces
  iface home inet dhcp
     wireless-essid rktmb
     wireless-key foobar

  iface work inet dhcp
     wpa-ssid wifiatwork
     wpa-psk ababababab

And then, in CLI:

  $ sudo ifup wlan0=home
or
  $ sudo ifup wlan0=work

to up the Wifi.

For convenience (we use Fedora/CentOS for all Linux boxes), I'm going to 
switch to Fedora 16 on my laptop, but really want to up the network via CLI.

What could be the Fedora equivalent?
Would you have some documentation link about that?

Thank you.
