[plug] file permissions

Well a lowercase "s" in the execute column of the user or group bits 
means an suid-user or suid-group binary respectively.
The "type" column is usually "-" (file) or "d" (dir) but can also be
"c" (char device)
"b" (block device)
"s" (unix socket)
"p" (named pipe / fifo)

I've never seen a cap "S" or a "t" before. Can you send in some ls -l 
output showing what files they're on and in what parts of the perms?
