When I want to install Drucall on my CentOS server there is a lot of manual work involved, downloading all the dependencies and installing the JavaScript files.

Why aren't all required JavaScript files defined in this module's hook_libraries_info()? Do you anticipate more WebRTC modules coming to Drupal that might need some of those dependencies and split them up for those reasons? I'd try to bring it down to this module.

If for some reasons you don't want to do that, could you perhaps update this (and the other modules) to have the .info-file's package property set to WebRTC (or Drucall)? Right now there are lot of categories on the module page all containing one module. It would be nice to have this bundled.
