CodeLister is a Perl CGI script for displaying a code library. To see an example of it in action, look here.
CodeLister displays all scripts from your library in a standard format, using a template. You can present a brief description or instructions along with the code.
The code itself is displayed in a textarea box with a button that allows the user to highlight all the text in the box for quick copying to the clipboard.
CodeLister can also be used for displaying license agreements or any other text that you'd like to make available for the user to copy.
Sure, it ain't fancy, but you can't beat the price!
