# Create a Munki "installs" array using the 'makepkginfo -f' tool from either a single file or multiple files by recursively searching an input directory.

# This is useful when deploying a custom package that installs files, as opposed to applications, and you want Munki to make sure they stay installed and unaltered.

# Output will be in 'InstallsArray.xml' on your desktop. Copy and paste the contents of this file into the Munki PkgInfo file for your package.

# Path to Munki's makepkginfo tool
