Write some Software

I keep a Google Blogger blog ( [login to view URL] ) and am looking for a tool or script or whatever to be able to automatically link keywords and phrases in posts with corresponding posts and pages in my blog. Much like this WP plugin "SEO Smart Links" [login to view URL] Like this menthioned tool it is to allow to set up own keywords and set of matching URLs, to set nofollow attribute and open links in new window, to set maximum number of links etc.
