String Searching Challenge

Write a program that takes two arguments at the command line, both strings. The program checks to see whether or not the second string is a substring of the first (without using the substr -- or any other library -- function). One caveat: any * in the second string can match zero or more characters in the first string, so if the input were abcd and the substring were a*c, then it would count as a substring. Also, include functionality to allow an asterisk to be taken literally if preceded by a \, and a \ is taken literally except when preceding an asterisk.
