*Path*

r#"You must use one of the following subcommands. Using this command as-is will only produce this help message.
There are three ways to represent a path:
* As a path literal, e.g., '/home/viking/spam.txt'
* As a structured path: a table with 'parent', 'stem', and 'extension' (and
* 'prefix' on Windows) columns. This format is produced by the 'path parse'
subcommand.
* As a list of path parts, e.g., '[ / home viking spam.txt ]'. Splitting into
parts is done by the `path split` command.
All subcommands accept all three variants as an input. Furthermore, the 'path
join' subcommand can be used to join the structured path or path parts back into
the path literal."#
