# By default ldirs lists all the sub-directories in the current directory
# in columns. It has the syntax:  ldirs [-h] [<path of directory>]
# -h will cause dot directories not to be listed
# specifying a directory path will list the sub-directories in the
# directory specified. ldirs --version  will print the version number of
# ldirs ldirs --help  will print a simple help message
