 Explore and manipulate paths.
 
-There are three ways to represent a path:
+## Signature
 
-* 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 an inner 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.
-
-## Usage
-```shell
-> path <subcommand> {flags} 
- ```
-
-## Subcommands
-* path basename - Get the final component of a path
-* path dirname - Get the parent directory of a path
-* path exists - Check whether a path exists
-* path expand - Expand a path to its absolute form
-* path join - Join a structured path or a list of path parts.
