Moved some functions from makepkginfo to munkilib so installcheck could use them. Added checking to installcheck, managedinstaller, and removepackages.py so they warn and exit if run by a non-root user. Added checks to installcheck and mamangedinstaller so that they exit if the other is running. git-svn-id: http://munki.googlecode.com/svn/trunk@87 a4e17f2e-e282-11dd-95e1-755cbddbdd66
