Estructura de Directorios del Código Fuente de Mozilla

El código para todos los proyectos de la familia Mozilla (como Firefox, Thunderbird, etc.) se combinan dentro de una sola estructura. La estructura contiene el código fuente y el codigo neceario para generar cada proyecto en las plataformas soportadas (Linux, Windows, Mac OS, etc).

Para simplemente dar un vistazo al código fuente de Mozilla, no es necesario descargarlo. Usted puede mirar y/o navegar el código fuente directamente desde MXR (Iniciar en http://mxr.mozilla.org/mozilla-central/source/ para visualizar el codigo completo de la rama HEAD) utilizando su navegador web.

Para modificar el código fuente, hay que adquirirlos ya sea descargando una imagen del código fuente o bien realizando una salida desde el control de de versiones actual (Mercurial).

Este documento describe la estructura de directorios que puede ser utilizada por client.mk -- es decir, directorios que son usados en alguno de los productos del proyecto. Hay otros directorios en el repositorio CVS de Mozilla, como las de herramientas web y los del código base clásico.

Estos no estan completamente actualizados.  Hecha un vistazo al resumen del directorio de codigo fuente para obtener una versión un poco diferente de la misma información (más vieja). También ver para obtener más detalle sobre las partes de Gecko.
