+ * ¡Estoy de celebración! He publicado mi primer libro:
+ * "Git y GitHub desde cero"
+ * - Papel: mouredev.com/libro-git
+ * - eBook: mouredev.com/ebook-git
+ *
+ * ¿Sabías que puedes leer información de Git y GitHub desde la gran
+ * mayoría de lenguajes de programación?
+ *
+ * Crea un programa que lea los últimos 10 commits de este repositorio y muestre:
+ * - Hash
+ * - Autor
+ * - Mensaje
+ * - Fecha y hora
+ *
+ * Ejemplo de salida:
+ * Commit 1 (el más reciente) | 12345A | MoureDev | Este es un commit | 24/04/2023 21:00
+ *
+ * Se permite utilizar librerías que nos faciliten esta tarea.
