prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  sharp-api
   +--app
   |   `--pages
   |       `--api
   `--test
  ```
  
  Convert this description:
  
  rebar3_app is a main directory that holds 2 subdirectories: _build and _checkouts.
  At the top level, '_build' encapsulates 1 subdirectories: default.
  In nested path '_build / default', 'default' houses 1 subdirectories: lib.
  At level 3, in directory path '_build > default > lib', 'lib' encapsulates 1 subdirectories that organize the source code.
  In nested path '_build > default > lib > dep', The 'dep' storage space is a vacant space.
  Back to the top level.
  At the top level, '_checkouts' carries 1 contained folders: dep.
  At level 2, in directory path '_checkouts > dep', 'dep' retains 1 folders: _build.
  In nested path '_checkouts → dep → _build', The '_build' storage space awaits content.
