I am nearly done with developing an R package, which makes it possible to include plantuml code in Markdown files which is than compiled into graphs. The repo is at https://github.com/rkrug/plantuml
and the website at https://rkrug.github.io/plantuml/index.html
The package obviously needs the `plantuml.jar` file to work properly. To make this for the user as easy as possible, I have included a function which downloads the `plantuml.jar` file automatically and stores it in a specific directory for usage in the package.
My question is: are there any specific requirements which I need to fulfil in that package to be in complicance with the package? Does the user has to agree to a license, before downloading, or is an automatic download in line with the plantuml license?
Thanks, and any feedback on the package is welcome,
