yaml2tree

Creates a tree of directories, specified using nested lists in YAML

Usage:

[mode=XXX] yaml2tree <yaml-file>

    mode=XXX       set this env var to provide a chmod-style octal value to use as file mode
                   for the created directories.

    <yaml-file>    path to YAML file containing the directory tree specification.
                   The YAML is a list of values, where every value is either a directory name
                   or a list of the same form. The YAML is processed top-down and whenever a
                   nested list is encountered, any directories in it are created inside the 
                   directory last seen on the outer list.

                   For example, the following definition -
                       - foo
                       -   - bar
                           - baz
                           - tam
                       - foo1
                       -   - bar2
                           -   - baz3
                       - soap

                   creates the following directory tree in the current working directory -
                       foo/
                           bar/
                           baz/
                           tam/
                       foo1/
                           bar2/
                               baz3/
                       soap/
