sha256sum for devhelp tarballs, please?

[srandalls]

I am using Debian Linux. Debian provides development packages which include *.vapi files, but not valadoc packages. So ...

I am writing a script to selectively pull Devhelp tarballs from the valadoc.org homepage which correspond to the *.vapi files on my system.

It would be helpful to be able to compare a sha256sum value for each available Devhelp in order to detect future available updates. Besides, this is a standard practice on sites offering downloads.

Thank you for your consideration of this request.
