Detailed Description

Pathname.

Note
For convenience Pathname is available as zypp::Pathname too.

Always stores normalized paths (no inner '.' or '..' components and no consecutive '/'es). Concatenation automatically adds the path separator '/'.

Todo
Add support for handling extensions incl. stripping extensions from basename (basename("/path/foo.baa", ".baa") ==> "foo")
