+/* The C Programming Language: 2nd Edition
+ * Exercise 1-23:
+ * "Write a program to remove all comments from a C program. Don't forget to
+ * handle quoted strings and character constants properly. C comments do not
+ * nest."
+ *
+ * I'm not sure why the instructions tell the reader to account for quoted
+ * strings and character constants. Comments always begin with either // or
+ * /*, so that sets the boundary of state.
+ *
+ * The states for this program are IN_MULTI for a multi-line comment,
+ * IN_SINGLE for a single line comment, and OUT for being outside a comment.
+ * These three states are all I need to determine whether I should output the
+ * contents of the C file or not. Characters are only output when the state is
+ * OUT, and there are conditions for getting into and out of comment state.
+ *
+ * I don't know of any other way to do this without invoking some higher-level
+ * libraries.
