+# scu-cli
+
+Consulta el Servicio de Comedores de la UGR desde la línea de comandos. Filtra con Flex++ el código fuente html de  https://scu.ugr.es/ para mostrar solo los menús deseados.
+
+## Requisitos
+Es necesario tener instalada la librería libcurl.
+
+## Compilación
+Si quieres hacer algún cambio en el programa instala Flex++, haz los cambios en plantilla.l y ejecuta  
+```$ flex++ plantilla.l```
+
+Para compilar con g++ en linux simplemente ejecuta en la carpeta del proyecto  
+```$ make```
+
+## Instalación
+Coloca el binario scu en algún directorio de tu PATH
+    
+## Uso
+```console
+$ scu -h
+Modo de empleo: scu [OPCION]... [DIA]
+
+La opción por defecto es mostrar el menú general del día actual
+
+	-a, --all         muestra todos los días disponibles  
+	-h, --help        muestra esta ayuda y finaliza  
+	-p, --pts         muestra los menús del comedor del pts
+	-f <file>         lee la información desde el fichero proporcionado
+
+El argumento DIA es un número entero entre 1 y 31, ambos incluidos.
+Si se proporciona se mostrarán solo los menús de este día si existe alguno.
+```
+## Ejemplos
+
+```bash
+# muestra el menú comedor del día actual
+$ scu
+
+# muestra el menú comedor del día 11
+$ scu 11
+
+# muestra el menú comedor (pts) del día 21
+$ scu --pts 21
+
+# muestra todos los menús del pts
+$ scu -a -p
+```
