+If you're used to doing things on the terminal (like I am) then having spaces in
+your files is extremely annoying. This script will take all the files or
+directories passed as arguments to it and replace the spaces with underscores
+(`_`).
+
+## TODO
+
+- Create a new argument that allows the user to set the replacement
+  character(s).
