I'm too lazy to provide that myself, but a patch for that could be considered for the gmt data package could be useful. That said, the whole arch-indep data set is probably much less a concerning for storage of some years ago, but that could be confirmed only by ftp-masters and mirror maintainers. There were some discussions in the past about a data providing infrastructure, but I missed the whole thread conclusion (if any). -- Francesco P.

If both programs use the same format for GSHHS you could simply suggest downloading by the same script in your documentation. Note that GMT coastlines format is quite known and used so i'm quite sure you can provide eventually some helper script for possible format conversions. -- Francesco P.
