mkpath (path, bool, perm)
Creates a directory path and returns a list of all directories
created. Takes the following arguments:
Name of the path or reference to a list of paths to create.
Boolean. If true, mkpath prints the name of each
directory as it is created. Default is false.
Numeric mode indicating the permissions to use when creating the
directories. Default is 0777.
rmtree (root, prt, skip)
Deletes subtrees from the directory structure, returning the number
of files successfully deleted. Symbolic links are treated as ordinary
files. Takes the following arguments:
Root of the subtree to delete or reference to a list of roots. The
roots, and all files and directories below each root, are deleted.
Boolean. If true, rmtree prints a message for each
file, with the name of the file and whether it's
using rmdir or unlink to remove
it (or if it's skipping the file). Default is false.
Boolean. If true, rmtree skips any files to which
you do not have delete access (under VMS) or write access (under
other operating systems). Default is false.
