If you write CGI programs in Perl, you probably find yourself using a lot of long print statements for outputting HTML. HTML uses a lot of double quotes, so it's better if you don't have to escape every " you use. You can accomplish this with the qq function, which will interpolate all variables but ignores double quotes. For example:
<BODY BGCOLOR="#FFFFFF" LINK="#003366" VLINK="#666666">
In this example, I've used ^ for a delimiter, but you can use anything you want.
