-## *gui* library
-
-The library contains functions for accessing the properties of UI elements. Instead of gui, you should use an object wrapper that provides access to properties through the __index, __newindex meta methods:
-
-Example:
-
-```lua
-print(document.some_button.text) -- where 'some_button' is an element id
-document.some_button.text = "new text"
-```
-
-```python
-gui.str(text: str, context: str) -> str
-```
-
-Returns translated text.
-
-```python
-gui.get_viewport() -> {int, int}
-```
-
-Returns size of the main container (window).
-
-```python
-gui.get_env(document: str) -> table
-```
-
-Returns environment (global variables table) of the specified document.
-
-```python
-gui.get_locales_info() -> table of tables where
- key - locale id following isolangcode_ISOCOUNTRYCODE format
- value - table {
-  name: str # name of the locale in its language
- }
-```
-
-Returns information about all loaded locales (res/texts/\*).
-
-## *inventory* library
-
-Library for inventories interaction.
-
-```python
-inventory.get(invid: int, slot: int) -> int, int
-```
-
-Requires an inventory ID and slot index. Returns item ID and count. ID = 0 (core:empty) means that slot is empty.
-
-```python
-inventory.set(invid: int, slot: int, itemid: int, count: int)
-```
-
-Set slot content.
-
-```python
-inventory.size(invid: int) -> int
-```
-
-Returns inventory size (slots number). Throws an exception if there's no inventory having specified ID.
-
-```python
-inventory.add(invid: int, itemid: int, count: int) -> int
-```
-
-Add an item to the specified inventory. Returns remaining count if could not to add fully.
-
-```python
-inventory.get_block(x: int, y: int, z: int) -> int
-```
-
-Returns block inventory ID or 0.
-
-```python
-inventory.bind_block(invid: int, x: int, y: int, z: int)
-```
-
-Bind inventory to the specified block.

-```python
-inventory.unbind_block(x: int, y: int, z: int)
-```
-
-Unbind inventory from the specified block.
-

-> Unbound inventories will be deleted on world close.
-
-```python
-inventory.clone(invid: int) -> int
-```
-
-Create inventory copy. Returns the created copy ID.
-
-```python
-inventory.move(invA: int, slotA: int, invB: int, slotB: int)
-```
-
-Move item from slotA of invA to slotB of invB. invA may be the same as invB.
-If slotB will be chosen automaticly if argument is not specified.
-
-## *hud* library
-
-
-```python
-hud.open_inventory()
-```
-
-Open player inventory
-
-```python
-hud.close_inventory()
-```
-
-Close inventory
-
-```python
-hud.open_block(x: int, y: int, z: int) -> int, str
-```
-
-Open block UI and inventory. Throws an exception if block has no UI layout.
-
-Returns block inventory ID (if *"inventory-size"=0* a virtual inventory will be created), and UI layout ID.
