+Checking the hashtable before loading the arguments is just in case all of the stdin
+is stuff that can be translated without needing to load all the arguments into the hashtable.
+Which should make the program go faster, right?
+
+If it isn't in the hashtable, it loads the translations from arguments until it finds the one
+it needs for the current line is has read from stdin, prints the replacement, and reads another
+line from stdin.
+
+If all of that fails, it will have loaded all of the arguments, gives up by just printing the
+line it got from stdin.
