-## *block* library
-
-```python
-block.name(blockid: int) -> str
-```
-
-Returns block string ID (name) by index.
-
-```python
-block.index(name: str) -> int
-```
-
-Returns block integer ID (index) by name.
-
-```python
-block.material(blockid: int) -> str
-```
-
-Returns the id of the block material.
-
-```python
-block.caption(blockid: int) -> str
-```
-
-Returns the block name displayed in the interface.
-
-```python
-block.get(x: int, y: int, z: int) -> int
-```
-
-Returns integer ID by block position
-
-```python
-block.get_states(x: int, y: int, z: int) -> int
-```
-
-Returns block state (rotation + additional information) as an integer.
-
-```python
-block.set(x: int, y: int, z: int, id: int, states: int)
-```
-
-Set block with specified integer ID and state (default - 0) at specified position.
-
-> [!WARNING]
-> `block.set` does not trigger on_placed.
-
-```python
-block.is_solid_at(x: int, y: int, z: int) -> bool
-```
-
-Check if block at the specified position is solid.
-
-```python
-block.is_replaceable_at(x: int, y: int, z: int) -> bool
-```
-Check if block may be placed at specified position. (Examples: air, water, grass, flower)
-
-```python
-block.defs_count() -> int
-```
-
-Returns count of available block IDs.
-
-Following three functions return direction vectors based on block rotation.
-
-
-```python
-block.get_X(x: int, y: int, z: int) -> int, int, int
-```
-
-Returns X: integer direction vector of the block at specified coordinates.
-Example: no rotation: 1, 0, 0
-
-```python
-block.get_Y(x: int, y: int, z: int) -> int, int, int
-```
-
-Returns Y: integer direction vector of the block at specified coordinates.
-Example: no rotation: 0, 1, 0
-
-```python
-block.get_Z(x: int, y: int, z: int) -> int, int, int
-```
-
-Returns Z: integer direction vector of the block at specified coordinates.
-Example: no rotation: 0, 0, 1
-
-
-```python
-block.get_rotation(x: int, y: int, z: int) -> int
-```
-
-Returns block rotation index based on used profile.
-
-```python
-block.set_rotation(x: int, y: int, z: int, rotation: int)
-```
-
-Set block rotation by index.
-
-### Extended blocks
-
-Extended blocks are blocks with size greather than 1x1x1
-
-```python
-block.is_extended(id: int) -> bool
-```
-
-Checks whether the block is extended.
-
-```python
-block.get_size(id: int) -> int, int, int
-```
-
-Returns the block size.
-
-```python
-block.is_segment(x: int, y: int, z: int) -> bool
-```
-
-Checks whether the block is a non-origin segment of an extended block.
-
-```python
-block.seek_origin(x: int, y: int, z: int) -> int, int, int
-```
-
-Returns the position of the main segment of an extended block or the original position,
-if the block is not extended.
-
-### User bits
-
-Part of a voxel data used for scripting. Size: 8 bit.
-
-```python
-block.get_user_bits(x: int, y: int, z: int, offset: int, bits: int) -> int
-``` 
-
-Get specified bits as an unsigned integer.
-
-```python
-block.set_user_bits(x: int, y: int, z: int, offset: int, bits: int, value: int) -> int
-```
-Set specified bits.
-
-```lua
-block.raycast(start: vec3, dir: vec3, max_distance: number, [optional] dest: table) -> {
-    block: int, -- block id
-    endpoint: vec3, -- point of the ray hit point
-    iendpoint: vec3, -- position of the block hit by the ray
-    length: number, -- ray length
-    normal: vec3 -- normal vector of the surface hit by the ray
-} or nil
-```
-
-Casts a ray from the start point in the direction of *dir*. Max_distance specifies the maximum ray length.
-
-The function returns a table with the results or nil if the ray does not hit any block.
-
-The result will use the destination table instead of creating a new one if the optional argument specified.
