##@brief Preloader for a multisite process
#
#This loader is a kind of fake loader. In fact it only read configurations
#for the multisite instance and then run a UWSGI process that will run
#the run.py file.
#
#If you want to see the "real" multisite loading process see
#@ref lodel/plugins/multisite/run.py file
#
#@par Implementation details 
#Here we have to bootstrap a minimal __loader__ context in order
#to be able to load the settings
#
#This file (once bootstraped) start a new process for uWSGI. uWSGI then
#run lodel.plugins.multisite.run.application function
#@note the uwsgi process in started using the execl function when UWSGI
#will exit this process will stop too
#
