Installing a package using guile script

[Reza Alizadeh Majd]

Hi, 

Just wanted to now if there is any programming interface available for Guix in 
order to
install a packages with a Guile script ? 

I actually want to install packages for a specific user, after `guix system 
reconfigure ... ` 
command. my plan was to add a simple Guile script after `operating-system` 
definition 
in my system configuration file, to add packages to user's profile.

the easiest way is to just run a shell script for to do that for me, but I'm 
curious that if there 
is any more programmatic solution for that?


Regards,
