| /** |
| * This header centralizes the declaration of our libcurl dependencies |
| * to make it easy to discover the oldest versions we support, and to |
| * inform decisions about removing support for older libcurl in the |
| * future. |
| * |
| * The oldest supported version of curl is documented in the "INSTALL" |
| * document. |
| * |
| * The source of truth for what versions have which symbols is |
| * https://github.com/curl/curl/blob/master/docs/libcurl/symbols-in-versions; |
| * the release dates are taken from curl.git (at |
| * https://github.com/curl/curl/). |
| * |
| * For each X symbol we need from curl we define our own |
| * GIT_CURL_HAVE_X. If multiple similar symbols with the same prefix |
| * were defined in the same version we pick one and check for that name. |
| * |
| * We may also define a missing CURL_* symbol to its known value, if |
| * doing so is sufficient to add support for it to older versions that |
| * don't have it. |
| * |
| * Keep any symbols in date order of when their support was |
| * introduced, oldest first, in the official version of cURL library. |
