$ make check # run the test suite
$ sudo make install # optional

To compile optional modules (such as Schnorr signatures), you need to run `./configure` with additional flags (such as `--enable-module-schnorrsig`). Run `./configure --help` to see the full list of available flags.

Usage examples
-----------
Usage examples can be found in the [examples](examples) directory. To compile them you need to configure with `--enable-examples`.
* [ECDSA example](examples/ecdsa.c)
* [Schnorr Signatures example](examples/schnorr.c)
* [Deriving a shared secret(ECDH) example](examples/ecdh.c)
* [Schnorr signatures example](examples/schnorr.c)
* [Deriving a shared secret (ECDH) example](examples/ecdh.c)
To compile the Schnorr signature and ECDH examples, you also need to configure with `--enable-module-schnorrsig` and `--enable-module-ecdh`.
