• hacked perl 4 perl 5 compatability code to use eval. (I'm going to give up on perl4 soon)

• added binmode to imgsize for PC - although I don't support PC's (unless it's running Linux :-)

• Added the following options
  • bool type to options array.
  • Proxies
  • Skip CGI
  • Script, InFilter and OutFilter as well as script
  • Makebackup, but didn't implement it yet.

• added version to top of file. Doh!

• got rid of all global variables - we'll apart from the option list
• it now runs with -w with no errors - no mean feat :-)
• make the image size getting routines return a 2 element array with either 0,0 or the width & height of the image
• added sys/socket.ph to the start so should work on solaris machines
• made stdout unbuffered so we can write bits at a time on the same line
• change the way the command line is used to support command line arguments in future
• now I only look at files with a length which look like text files
• added the following options (may still be unimplemented, but you can set them!)
  • UpcaseTags * upcase all HTML tags
  • TryServer * if you can't find the file try the server? needs base tag
  • QuoteNums * quote the numbers when you insert them
  • Munge% - if a % is there do you want to to get rid of it?
  • NeedAlt * complain if no alt tag present
  • Base * to specify the base to use if we can't find the file
• New output format fits each image on one line - looks nice - tells you what the tags were and will be
• It actually recognizes if you have a base tag - although does nothing with it :-)
• now it matches IMaGe's and FIGUREs (HTML3)
• regexp to match an IMG or figure is much better
• The chown code is much tider - proper use of stat
• new istrue and isfalse functions for checking options values
• replaces old attributes if they are there - keeping formatting - or inserts new attributes at start of TAG. It only insert width & height rather than rebuidling the line from $one -> $seven.
• the base tag is recognized and if present the whole page it fetched using HTTP - do you really want this - some browsers don't even support the base tag! (A la Lynx)
• If the file cannot be found it tries to contact the server to ask it for that file - this gets around server path translation problems
