// This program takes a list of files and directories (indicated by a
// trailing slash) on the stdin, and prints to stdout each input
// filename along with its desired uid, gid, and mode (in octal).
// The leading slash should be stripped from the input.
//
// Example input:
//
// system/etc/dbus.conf
// data/app/
//
// Output:
//
// system/etc/dbus.conf 1002 1002 440
// data/app 1000 1000 771
//
// Note that the output will omit the trailing slash from
// directories.
