## cinterop tool specifics
The **cinterop** tool produces `.klib` wrappers for native libraries as its main output.

## The library format
**WARNING**: the library format is *very* preliminary. It is subject to change right under your fingertips. And it can include changes which will make it incompatible between releases at least until Kotlin/Native is stabilized.
Kotlin/Native libraries are zip files containing a predefined
directory structure, with the following layout:
