Automatic update system

[vnr]

Hello,

I have a program written in D which is open-source on GitHub.

I would appreciate it if, when I release a new version, users 
would be notified by the program and that it offers an automatic 
update, i.e. the user doesn't have to reinstall the whole 
repository himself, but that it is updated automatically.

I haven't found any packages that directly meet my needs, but in 
the meantime I imagine that I will have to use the GitHub API, as 
well as Curl to make such a system.

Do you have any resources or suggestions as to how I could 
implement this? Thank you!
