netprofiles0.2 "alpha release"

I'll get straight to the point, here are the tars:
netprofiles0.2 - use this to install the core scripts (it will untar to / unless otherwise told)
netprofiles0.2-NMcaller - This contains the NM caller (no bash script)
MyProfiles - My sample profiles (full,home,public,hidden)
you will also need to add a script to /etc/NetworkManger/dispatcher.d/ such as

#!/bin/sh
pkill chooseprofile.py
/etc/netprofiles/callers/NetworkManager/chooseprofile.py $2
exit 0

or netprofiles0.2-full - Everything including the bash script (it will untar /)


once installed you may want to make a link for set_uuid_profile.py as it is a program to be used by humans.

sudo ln -sv /etc/NetworkManager/callers/NetworkManager/set_uuid_profile.py /usr/bin/set_uuid_netprofile

I'm using and testing it on my computer but I haven't done extensive tests as I don't use all the features and don't know if anybody else is going to use it so consider the software untested.


License:
Do little scripts like this need a license? Is it worth GPLing something that is by its very nature open? I've assumed that its public domain on account of them being small scripts however if they can be licensed then the main script is derived from my /etc/rc so my code is under the same license.

Documentation:
I will add manpages in v0.3 if people start using it.

unfortunately as I couldn't find what a default Ubuntu or fedora install looks like without messing around with liveCDs, the offline profile is empty

Access:
I'm not sure on the best way to give access to the code, if people start using it I will look into git/svn hosting or hosting it locally.
