Es­te script es un muy sim­ple ve­ri­fi­ca­dor de li­nks que se ase­gu­ra que las pá­gi­nas que Niko­la ge­ne­ra no ten­gan li­nks ro­to­s. Va a ser par­te de Niko­la pro­pia­men­te di­cho una vez que es­té más pu­li­do y doit so­por­te lis­tar los tar­ge­ts

Para probarlo, bajalo y ejecutálo desde el mismo lugar donde está tu conf.py, inmediatamente después de un doit.
