I made another repository. This time I tried to make a special repository just for one program: FFPlay
For this I preset almost every value except the version. For the version I grep the thread linked above, search the "Last Edit: "-line under the first post and convert this to a time.
I am quite sure the script will not work tomorrow anymore, because the date followed by "Last Edit: " is not everytime just a date. For older dates it is but for recent edits "Today" is shown, which I handle right now.
I assume tomorrow "Yesterday" will be the date and then my script will fail. But I will see. And if the script works for some days, I can make mini-repositories for other release-threads, too. Or you as local script or hosted on your own server
As always add it yourself:http://ziz.gp2x.de/gcw-repos/ffplay.py
