+# It creates a folder structure in home for the current date in the following format:
+# $HOME/ByDate/<Year>/<Month>/<Day>
+
+# It also sets up a symlink in home: $HOME/Today
+# This symlink will always point to the folder for the current date.
+
+# Finally, it removes any folders without data, to prevent clutter.
+
+# - Why did you make this?
+# I remember things better when they have a date attached to them.
+# You can use this for a primitive form of note-taking, but aside from notes -
+# you can store any data this way.
