Hi, 

I've some trouble with guix pull use: 

i have cloned a guix repo to had my package in gnu/packages in order to have them in 'guix package - A' list. 

before guix 0.13, I used guix pull like this : 

> guix pull --url="http://gitlab.com/my-acount/my-repo/repository/archive.tar.gz?ref=master" 

but know it doesn't work anymore.. guix pull do not use tarball anymore 

you can see at this commit : http://git.savannah.gnu.org/gitweb/?p=guix.git;a=commit;h=59a16275189f55ddd692b0ea5b415c706fa1fd69 

The use of guix pull change but it doesn't change in the manual... 

It's why i need some help to know how to use guix pull with its options --commit and --branch 

thanks for yours future answer
