How do I download all releases (in fact all tags) of a project at a time?

I need to download all releases (in fact all tags) of a project from github repository. So I need commands or scripts that provide all the tag names of a given project and download them automatically.

Solution

Clone the entire git repository to a local directory on your machine with git clone --no-single-branch
Now you have all the data downloaded in git format
Use the git tag command to list all the tags
Use the git archive command to create an archive (tar or zip) of each tagged release (Hint: Use shell or batch scripting to loop over the output from git tag)
