Attached is the script Fedora Unity uses to jigdofy it's Re-Spins. Note 
the "function jigdofy()" in the top that may just help you get the 
syntax right.

Note the double slash in the two directories passed to the "jigdo-file 
make-template" command, which functions as a delimiter for jigdo-file, 
so that in the --label parameter, we can 'label' the path and then 
attach a URI (--uri) to be used in the resulting .jigdo file instead.

$1 is the (fully qualified) path to the .iso image,
$2 is the base architecture for the .iso image (i386, x86_64 or ppc in 
our case), and
${version} is the Fedora $releasever (9 or 10 right now).

Also note that /data/os/distr/fedora is a local, full mirror and that 
/data/os/archive/fedora is a local, full archive (with package files 
that have been removed from the mirror because for example they've 
expired and have been superseeded by another update to said package).

Kind regards,
