#   make           compila los programas de la clase en build/
#   make lab       compila el laboratorio en build/lab/
#   make hunt      compila los programas de la cacería en build/hunt/: con sanitizers,
#                  y con el sufijo _vg para valgrind (-g -O0, sin sanitizers)
#   make test      corre las pruebas de los ejemplos y de los apuntes
#   make test-lab  prueba su laboratorio; falla hasta que lo terminen
#   make clean     borra lo generado
#
# Los programas de errors/ tienen errores a propósito. No se compilan con make:
# los compilan las pruebas, y ustedes, con los comandos de los apuntes.
