I haven't much experience with TeX/LaTex and I am trying to write a CV based on this repository.
Specifically, I am trying to understand how a LaTeX class file is written, and reproduce to a certain extend the class file of this repository, since it is quite similar with what I would like to do.
I cannot understand the code in lines 96 and 99. What is the purpose of defining a command and then redefining it? I also cannot understand what the command does, and it doesn't seem that the author uses it somewhere.
Can someone explain briefly?
