I think you are correct. I run GuixSD and, after installing parallel I get ... *** g1@g1 ~$ ls | parallel echo Academic tradition requires you to cite works you base your article on. If you use programs that use GNU Parallel to process data for an article in a scientific publication, please cite: O. Tange (2011): GNU Parallel - The Command-Line Power Tool, ;login: The USENIX Magazine, February 2011:42-47. This helps funding further development; AND IT WON'T COST YOU A CENT. If you pay 10000 EUR you should feel free to use GNU Parallel without citing.
