## What exactly do -ldiscord and -lcurl do?
# -ldiscord is a flag that tells the linker to look for a library called "discord."
# the linker looks for these libraries in the /usr/lib/ directory, and,
# if it finds them, it links them into the binary.
# Here the linker finds /usr/local/lib/libdiscord.a through -ldiscord. 
# so, basically, a .a file is an "archive." I know that sounds dumb, but, back in the day,  
# you could actually use what we now call "C libraries" as backup files... really.   
# so, the linker just expands that archive file 
# (the same way that a tarfile would get expanded, or, Windows Explorer expanding a zipfile), and, 
# it reads all of the symbol tables in all of the objects in there. \ 
# one of those is gonna contain the function you're after, so, 
# the linker picks that object file and links it into the binary.
