+# path
+Explore and manipulate paths.
+
+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 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.
+* path parse - Convert a path into structured data.
+* path relative-to - Get a path as relative to another path.
+* path split - Split a path into parts by a separator.
+* path type - Get the type of the object a path refers to (e.g., file, dir, symlink)
