# Object-Oriented Pathname Class

# Author:: Tanaka Akira <akr@m17n.org>

# Pathname represents a pathname which locates a file in a filesystem.
|

# It supports only Unix style pathnames.
|
|
#
|
|
# Pathname is immutable. It has no method for destructive update.
|
|
#
|
|
# pathname.rb is distributed with Ruby since 1.8.0.
