v2.0.1

Minor cleanup, tests updated to use Nim v1.

v2.0.0

Adds unveil(2) support which can be used as follows:

unveil("/foo/bar", {Permission.Read, Permission.Write, Permission.Execute})

Passing an empty string and an empty set of promises is the same as unveil(NULL, NULL) in C, disabling future calls to unveil:

unveil("", {})

v1.1.0

Refactor to make the main pledge call a macro. This means that the promise string is computed at compile time rather than run time.

1.0.2

Adding docs to readme.
