pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const email = try chilkat.Email.init();

    // Load an email from a .eml
    email.loadEml("embeddedEmail.eml") catch {
        std.debug.print("{s}\n", .{try email.getLastErrorText(alloc)});
        return;
    };

    // Display how many attached emails are embedded within
    // this one:
    const num_attached = email.getNumAttachedMessages();
    std.debug.print("numAttached = {d}\n", .{num_attached});

    // Get the 1st attached message.
    const email2 = try chilkat.Email.init();
    defer email2.deinit();
    if (email.getAttachedEmail(0, email2)) {
        // Display the subject, From, and a header field...

        std.debug.print("{s}\n", .{try email2.getFrom(alloc)});
        std.debug.print("{s}\n", .{try email2.getHeaderField(alloc, "X-SOMETHING")});
