How to update a deployed fbone/flask app?

[devsatish]

I have a web-app written with fbone framework (/var/www/flaskapp) . I have a screen in the web-app, where the user can upload a new version of the web-app as a zip

my plan is to have a function in the views.py, which takes the uploaded zip file and unzips to web-app folder (/var/www/flaskapp)

Question: do i need to run fab setup ? or is there a way to just put a updated distribution egg file?
