package sysfs

import "github.com/tetratelabs/wazero/internal/sysfs"

Package sysfs includes a low-level filesystem interface and utilities needed for WebAssembly host functions (ABI) such as WASI.

The name sysfs was chosen because wazero's public API has a "sys" package, which was named after https://github.com/golang/sys.
