This adds a special CWD file descriptor, AT.FDCWD (-2), to refer to the current working directory. The `*at(...)` functions look for this and resolve relative paths against the stored CWD. Absolute paths are dynamically matched against the stored Preopens. "os.initPreopensWasi()" must be called before std.os functions will resolve relative or absolute paths correctly. This is asserted at runtime. Support has been added for: `open`, `rename`, `mkdir`, `rmdir`, `chdir`, `fchdir`, `link`, `symlink`, `unlink`, `readlink`, `fstatat`, `access`, and `faccessat`. This also includes limited support for `getcwd()` and `realpath()`. These return an error if the CWD does not correspond to a Preopen with an absolute path. They also do not currently expand symlinks.
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

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.
