-The "dylink" section is defined as:
+The "dylink.0" is a custom section, the existence of which signals that the

+A "dylink.0" consists of a series of sub-sections using the same format as found
+in the ["names"][names_sec] section:

+- `2 / WASM_DYLINK_NEEDED` - Specifies external modules that this one depends on.

+For `WASM_DYLINK_MEM_INFO` the following fields are present in the

 ## Interface and usage
 
 A WebAssembly dynamic library must obey certain conventions.  In addition to
