Directories

The directory management utilities are:

•   (current-directory path) sets the current working directory to path and returns #<void>. If no path argument is provided, the name of the current working directory is returned. If path cannot be made the current directory, the  exn:i/o:filesystem:directory exception is raised.
•   (directory-exists? path) returns #t if path refers to a directory or #f otherwise.
•   (make-directory path) creates a new directory with the pathname path, returning #t if a directory is created successfully or #f otherwise.
•   (delete-directory path) deletes an existing directory with the pathname path, returning #t if the directory is deleted successfully or #f otherwise. The directory must already be empty.
•   (directory-list path) returns a list of all files and directories in the directory specified by path. If no path is provided, a list of files and directories in the current directory is returned.
•   (filesystem-root-list) returns a list of all current root directories.
