Re: #pragma once?

[Zoltan Borok-Nagy]

+1 for #pragma once since it's cleaner and less error-prone.

Permits on documentation

[carlos boceta]

good afternoon ,

I am new to this project, with programming knowledge of c and java.

I would like to collaborate as a first contact with the translation into 
Spanish of the software documentation.

Could you have permissions on the wiki?

In the same way, I would like to have some documentation about the architecture 
that you are using to, little by little, be able to collaborate with the code 
part.


Greetings and thank you

Hi Carlos, thanks for your interest! The wiki is mostly the documentation
for developers, not users. User documentation is within the docs directory
of the git repo.

What is your wiki username?

http://cidrdb.org/cidr2015/Papers/CIDR15_Paper28.pdf is an overview of the
architecture from a few years ago
