URL Utility

Brief:
    This program can do basically two things- it can list all src and href (not case sensitive) values in an html file (basically it looks for the sequence " src" and " href" but it does not deal with ".src" and ".href") and it can also convert relative URLs into absolute URLs. This program comes really handy if you are maintaining a website (I use it with a shell script)- I code internally using relative URLs so that I can check my links even though I have no internet access and I just create the copy I would be uploading using the script.

How to use:
Program Usage
-to print this instructions run the program with no additional parameter
-to print all href and src values in a given html file, run the program with
    an additional parameter being the file name ie the command:
       <executable name> index.html
    prints out all href and src values in index.html
-to prefix a string to all URL values in a file and the output is in another
    file do something like this-
       <executable name> f1.html f2.html http://cookiebreak.tripod.com
    this would attach http://cookiebreak.tripod.com to all URL values
    (except those starting with "www.", "http://", "ftp://", "mailto:")
    in f1.html and the output is f2.html
-to ignore all URLs that starts with certain keywords do something like this
       <executable name> f1.html f2.html http://cookiebreak.tripod.com k1 k2 kn
    this would do as the previous command except that it ignores all
    that starts with k1, k2 and kn
