## Symbols optimizer (wasm-opt)
```
cargo run --release --bin wasm-opt -- <contract.wasm>
cargo run --release --bin wasm-opt -- <input_binary.wasm> <output_binary.wasm>
```
This will optimize WASM symbols tree to leave only those elements that are used by contract `call` function entry.

For development puposes, raw WASM contract can be injected with gas counters (the same way as it done by Parity runtime when running contracts)
```
cargo run --release --bin wasm-gas -- <contract
cargo run --release --bin wasm-gas -- <input_binary.wasm> <output_binary.wasm>
```
## Allocators substiution (wasm-ext)
Parity WASM runtime provides simple memory allocators, if contract requires. When relied on this allocators, WASM binary size can be greatly reduce. This utility scans for `_malloc`, `_free` invokes inside the WASM binary and substitutes it with invokes of the imported `_malloc`, `_free`. Should be run before `wasm-opt` for better results.
```
cargo run --release --bin wasm-ext -- <input_binary.wasm> <output_binary.wasm>
```
## API
All executables use corresponding api methods in the root crate and can be combined in other build tools.
