This is as far as I got before giving up due to libcurl's low level
interface (std.net.curl doesn't have a way to upload a file with extra
fields, if it did this would have been amazingly simple):

#!/usr/bin/rdmd

import std.stdio, std.net.curl, std.string, std.json, std.conv;
import etc.c.curl;

void main(string[] args)
{
    write("GitHub username: ");
    auto username = readln().chomp();

    write("GitHub password: ");
    auto password = readln().chomp();

    write("GitHub repo: ");
    auto repo = readln().chomp();

    write("Description: ");
    auto desc = readln().chomp();

    write("MIME type: ");
    auto mime = readln().chomp();

    auto client = HTTP();
    client.setAuthentication(username, password);

    auto create_url = "https://api.github.com/repos/"; ~ username ~ "/" ~
repo
        ~ "/downloads";

    auto create_json = format(
            q"#{ "name": "%s", "size": %d, "description": "%s",
            "content_type": "%s" }#",
            args[1], File(args[1]).size(), desc, mime);
    auto create_response = post(create_url, create_json, client);
    auto cj = parseJSON(create_response);

    Curl curl;
    curl.initialize();
    curl.set(CurlOption.url, cj["s3_url"].str);


    // missing from etc.c.curl
    enum CURLFORM_COPYNAME = 1;
    enum CURLFORM_COPYCONTENTS = 4;
    enum CURLFORM_FILE = 10;
    enum CURLFORM_CONTENTTYPE = 14;
    enum CURLFORM_END = 17;

    curl_httppost *post=null;
    curl_httppost *last=null;
    void formadd(string key, string value) {
        curl_formadd(&post, &last, CURLFORM_COPYNAME, key.toStringz(),
                CURLFORM_COPYCONTENTS, value.toStringz(), CURLFORM_END);
    }
    formadd("key",                   cj["path"].str);
    formadd("acl",                   cj["acl"].str);
    formadd("success_action_status", "201");
    formadd("Filename",              cj["name"].str);
    formadd("AWSAccessKeyId",        cj["accesskeyid"].str);
    formadd("Policy",                cj["policy"].str);
    formadd("Signature",             cj["signature"].str);
    curl_formadd(&post, &last,
            CURLFORM_COPYNAME, "Content-Type",
            CURLFORM_CONTENTTYPE, cj["mime_type"].str.toStringz(),
            CURLFORM_END);
    curl_formadd(&post, &last,
            CURLFORM_COPYNAME, "file",
            CURLFORM_FILE, args[1].toStringz(),
            CURLFORM_END);
    curl_formadd(&post, &last,
            CURLFORM_COPYNAME, "name",
            CURLFORM_COPYCONTENTS, cj["name"].str.toStringz(),
            CURLFORM_END);
    curl.set(CurlOption.httppost, post);
    curl.onProgress = delegate int(size_t dltotal, size_t dlnow, size_t
ultotal,
            size_t ulnow)
    {
        writeln("Progress: uploaded bytes ", ulnow, " of ", ultotal);
        return 0;
    };
    curl.perform();
    curl_formfree(post);
}
