How do I create a new file on a remote host in fabric (python deployment tool)?

Question

I\'d like to create a file with the name passenger_wsgi.py on a remote host. I\'d like to use the following string to create the file\'s content:

\'\'\'
import s

What I do is have the file locally as something like "app.wsgi.template".

I then use tokens in the file, like:

import sys, os

sys.path.insert(0, "/ruby/$HOST$/www/$HOST$/django-projects")
sys.path.insert(0, "/ruby/$HOST$/www/$HOST$/django-projects/project")

import django.core.handlers.wsgi
os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings'
application = django.core.handlers.wsgi.WSGIHandler()

I use fabric to "put" the file over to the remote host, then use "sed" (or equivalent functions in Python) to replace the "$HOST$" and "$USER$" tokens with the values I want.

run("sed -i backup -e 's/$USER$/%s' -e 's/$HOST$/%s' app.wsgi.template" % (user, host))
run("mv app.wsgi.template app.wsgi")
