The fs_tool component performs a sequence of file operations on a locally
configured VFS. The file operations are given the configuration as follows:

! + config | exit: yes
!   + vfs
!     ...
!   + new-file | path: /path/to/file
!     :
!     : Content to write to the file
!     :
!   + remove-file | path: /path/to/file
!   + remove-dir  | path: /path/to/dir
!   + create-dir  | path: /path/to/new/dir
!   + create-dir  | path: /path/to/existing | to: /path/to/new/name

Setting the 'exit' attribute to 'yes' instructs the component to exit after
completing the sequence. Otherwise, the component keeps responding to
configuration changes by executing the operations found in the updated
configurations.

The 'new-file' operation creates the new file or overwrites the existing file
given through the 'path' attribute with the content that is given inside the
tag.

The 'remove-file' operation removes the existing file given through the 'path'
attribute.
