pequeño servidor gemini en go
|
||||
|
||||
basado en el ejemplo de servidor de [go-gemini](https://git.sr.ht/~adnano/go-gemini) y algunos aspectos del servidor de [flounder](https://git.alexwennerberg.com/flounder/)
|
||||
|
||||
# config
|
||||
|
||||
el servidor espera una configuración con el siguiente formato, para indicar los hosts que existirán y desde dónde se servirán:
|
||||
|
||||
```
|
||||
example.com /var/gemini/ejemplo
|
||||
otrohost.com /var/gemini/otroejemplo
