Unfortunately Blackmagic Design company has changed their download
mechanism to use only a web page that requires name & email details of
the downloader; then issues some sort of download authority so that wget
could be used. However that authority it is time limited, so not worth
adding that to the .info file.
It has been that way for a while for newer versions and I held the
version back at 10.1.4 purely because it was still directly
downloadable. Looks like they've eventually realised and closed that
This is, more or less, the same situation as the SlackBuild for jdk; the
DOWNLOAD file must be downloaded separately first.
An alternative would be to host the download file somewhere else like
slackbuildsdirectlinks but there may be legal implications to consider.
Any insights welcome ...
