This is a library for generating form letters, building HTML pages, or filling in templates generally. A `template' is a piece of text that has little Perl programs embedded in it here and there. When you `fill in' a template, you evaluate the little programs and replace them with their values. Here's an example of a template: Dear {$title} {$lastname}, It has come to our attention that you are delinquent in your {$monthname[$last_paid_month]} payment. Please remit ${sprintf("%.2f", $amount)} immediately, or your patellae may be needlessly endangered. The result of filling in this template is a string, which might look something like this: Dear Mr. Gates, It has come to our attention that you are delinquent in your February payment. Please remit $392.12 immediately, or your patellae may be needlessly endangered.
