download_mkdir

download_mkdir   dirname

Ensures that $dirname exists. Won't cause an error if the directory is already there. Better than the stardard mkdir because it will make all the directories leading up to $dirname

Source code:

  
    set dir_list [split $dirname /]
    set needed_dir ""
    foreach dir $dir_list {
        if [empty_string_p $dir] {
            continue
        }
        append needed_dir "/$dir"
        if ![file exists $needed_dir] {
            ns_mkdir $needed_dir
        }
    }
