+ * @brief Convert a string to a 'char**' representing an argument list
+ *
+ * This function takes a string 'var' and converts it into a 'char**'
+ * representing an argument list. The argument list can be consumed by
+ * functions like 'execvp'.
+ *
+ * @param[in] var The string to be converted
+ * @param[in] flags Flags controlling the behavior of the conversion
+ *
+ * @return A 'char**' representing the argument list
+ *
+ * The function uses the 'wordexp' function to perform the conversion. The
+ * 'flags' argument controls the behavior of the 'wordexp' function. The
+ * returned 'char**' is dynamically allocated, and must be freed by the
+ * caller using 'delete[]'.
