Here's a quick starting point for your Android app manifest according to Facebook's established best practices.

facebook.py

import re
import urllib2
from BeautifulSoup import BeautifulSoup

PERMISSIONS_URL = 'http://developer.android.com/reference/android/Manifest.permission.html'

NON_THIRD_PARTY = 'Not for use by third-party applications.'

MANIFEST_START = ("<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                  "<manifest xmlns:android=\"http://schemas.android.com/apk/res/android\"\n"
                  "    package=\"com.facebook.katana\">\n")
MANFEST_END = "</manifest>"
MANIFEST_PERMISSION = "    <uses-permission android:name=\"%s\" />"

page = BeautifulSoup(urllib2.urlopen(PERMISSIONS_URL).read())

permissions = page.findAll(True, {'class': re.compile(r'\bjd-details\b[^-]')})

print MANIFEST_START

for permission in permissions :
    description = permission.findAll(True, {'class': 'jd-tagdata jd-tagdescr'})[0].getText()
    if NON_THIRD_PARTY not in description :
        data = permission.find(True, {'class': 'jd-tagdata'})
        if data is not None:
            print MANIFEST_PERMISSION % re.findall('\"(.*)\"', data.getText())[0]

print MANFEST_END
