Hi all,
just a brief comment while seeing this change to the Debian wiki page. "Not
flexible enough" is very open-ended and calls for continuous updates of watch
files that work perfectly at the moment of their update.
I think that all of this suggests that we would benefit of having this
complexity transferred to uscan: if the file looks like a compressed tar
archive, like 'foo.tar.gz', then look for other common compressions or formats
if no file is found.
My concern is that the entries in the watch files are getting dense, where the
informative part ('foo') gets shadowed by the flexible part
('\.(?:zip|tgz|tbz|txz|(?:tar\.(?:gz|bz2|xz)))'), which is why usually I do not
follow the recommendation above.
Cheers,
