Instructions:
--------------------------------------------------------
Just download the file 'marionnet_from_scratch', then:

$ chmod +x marionnet_from_scratch 
$ ./marionnet_from_scratch

If you don't have neither 'sudo' nor 'su' and you want to install 
into a system directory (option -p), please execute the script as root.

Options:
--------------------------------------------------------
You can also tune the script behaviour by using options
(if your Internet connection is slow, you probably want -F):

$ ./marionnet_from_scratch --help
Usage: marionnet_from_scratch [OPTIONS]

Download, compile and install marionnet and its principal dependencies.
In addition to compile-time dependencies, when a run-time dependency
like 'vde' or 'dot' seems not installed, the script automatically
downloads, compiles and installs it from the appropriate project homepage
or from our mirror (i.e. http://www.marionnet.org/download/mirror/).

  -p, --prefix PATH		Set the installation prefix
  -t, --tmpdir PATH		Set the temporary working directory
  -c, --continue PATH		Continue execution started in PATH

  -h				Print this message and exit

  -G, --godi VERSION		Set godi's version
  -l, --lablgtk VERSION         Set lablgtk's version
  -v, --vde VERSION             Set vde2's version
