Este proyecto sirve de guía para la creación de una nueva librería.



1. Antes de importar el proyecto, en el fichero `pom.xml`:

	* Reemplazar `template` por el nombre que se le quiere dar a la librería.

	* Definir convenientemente `name`, `description` y `artifactId`.

	* Definir la versión de `redmic` (en la sección `parent`) con la más reciente.



2. Importar como proyecto maven.



3. Remplazar `template` por el nombre adecuado en la primera línea de este mismo fichero.



4. Añadir las dependencias deseadas.



5. Añadir en `src/test/java/es/redmic/` y `src/main/java/es/redmic/` un nuevo package con el nombre de la librería, como base donde se añadirá el código.



6. Añadir al fichero `pom.xml` del proyecto padre (`es.redmic.lib.libs`), el nombre de la nueva librería.



7. Actualizar la tabla inicial de estado, eliminar estas instrucciones y documentar adecuadamente.
 
Este proyecto tiene como objetivo añadir soporte para serialización/deserialización de objetos JTS vía jackson
