This brings two quality-of-life improvements for folks working on
compile error test cases:
- test cases can be added/changed without re-building Zig
- wrapping the source in a multi-line string literal is not necessary
I decided to keep things as simple as possible for this initial
implementation. The test "manifest" is a contiguous comment block at the
end of the test file:
1. The first line is the test case name
2. The second line is a blank comment
2. The following lines are expected errors
Here's an example:
```zig
const U = union(enum(u2)) {
A: u8,
B: u8,
C: u8,
D: u8,
E: u8,
};
export fn entry() void {
_ = U{ .E = 1 };
}
// union with too small explicit unsigned tag type
//
// tmp.zig:1:22: error: specified integer tag type cannot represent every field
// tmp.zig:1:22: note: type u2 cannot fit values in range 0...4
```
The mode of the test (obj/exe/test), as well as the target
(stage1/stage2) is determined based on the directory containing the
test.
We'll probably eventually want to support embedding this information
in the test files themselves, similar to the arocc test runner, but
that enhancement can be tackled later.

License
The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
