NOX_INSTALL

-NOX Install on deb testing:
-
-Install deps:
- sudo apt-get install autoconf automake g++ libtool python  python-twisted swig  libxerces-c2-dev libssl-dev make python-dev libboost-filesystem1.38-dev libboost1.38-dev libboost-test1.38-dev
-
-Get NOX repo:
- git clone git://noxrepo.org/nox
- cd nox
-
-If you don't need all the libraries, just the coreapps (faster build):
- ./boot.sh --apps-core
-If you do need all the libraries:
- ./boot.sh
-
-Build
- mkdir build/
- cd build/
- ../configure --with-python=yes
-
-Run w/pyswitch:
- cd src
- ./nox_core -i ptcp: pyswitch
-
-Kill (not name to kill is different than name to load):
- sudo killall lt-nox_core
