+Cody fixed this in the case that the program is compiled or linked/copies to
+another file name: the code constructed the source code file name in a clever
+and more obscure way by copying to the buffer `*argv` and then using `strcat(3)`
+to concatenate to it `.c`. But this assumes that the executable is the same name
+as the source file which isn't always be true. The author even stated: 'as long
+as the source is in the same directory as the executable it should be able to
+find it' but the source code file name is not always the same as the executable
+with the appropriate extension so this might be called a bug fix as well though
+if one runs it from another directory, specifying the directory, it'll not catch
