grab.cpp

/*
 * The C++ part handles all the layout calculations and printing.
 * The shell script (under shell_script variable) is the script that fetches the info
 *
 * The reason for using a shell script for fetching is its simpler to expand on.
 * Additionally shell scripts already exist for this job (making use of neofetch's functions here)
 *
 * Reason for not doing the printing in shell is because its simply too slow for such a
 * cosmetic interface.
 *
 * When this program is run (with no arguments), it executes the shell script. The scripts
 * fetchs the info and sets them as environment variables.
 * The script re runs this program (with an arbitrary argument) with the new environment variables 
 * and hence C++ can fetch the variables.
 *
 * There must be a much more efficient way to do this, but this is what I was able to come up with
 * as this is my first fetch script :D
