+ * argv_parse.c --- utility function for parsing a string into a
+ * argc, argv array.
+ *
+ * This file defines a function argv_parse() which parsing a
+ * passed-in string, handling double quotes and backslashes, and
+ * creates an allocated argv vector which can be freed using the
+ * argv_free() function.
+ *
+ * See argv_parse.h for the formal definition of the functions.
