Creating new package for Guix - newbie's question

[Rodion Goritskov]

Hello everybody!

I am GuixSD and Guix newcomer. Installation succeeded, but suddenly I 
found that one of my favorite packages - compton[1], is missing in 
repos.

OK, that is not really a problem - I tried to create this package 
myself. So, I copied template "hello.scm" from documentation, modified 
it according to compton's build process.

Question is - how I can test created package build process?

I tried executing guix package -f <my package file>. It doesn't output 
any errors, but package is not installed or built.

What is the process of testing created package file?

Thank you in advance.

Proud Guix user,
Rodion Goritskov

P.S. Guix and GuixSD are great pieces of software!
