+This is a simple program I made because I am lazy.
+It grabs all the source files in a given directory
+recursively, grabbing any source files in child
+directories and outputting them to be taken as the
+input into gcc.
+
+Usage:
+    sourcefiles <path> <File extension 1> [File extension 2 ...]
+
+Example:
+    $ sourcefiles ~/Projects/lmc/ h cpp
+    > /home/ben/Projects/lmc/src/cpu.h /home/ben/Projects/lmc/src/main.cpp /home/ben/Projects/lmc/src/main.h 
+
+Peak lazyness but it works
