Requirements for using plantuml in R package to create xml graphs?

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 and the website at .

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,

Thanks for your work on the R package !

We are very open, so there are no specific requirements to fulfil. You can automatic download the jar file, this is compliant with our rules.
