Update (4/1/2008): I finally did this. My steps:
- Download latest syntax highlighting code
- Expand .rar with WinRAR
- Uploaded all the syntax highlighting files to Google Pages
- Followed instructions here to change my Blogger template. (NOTE: remove errant link close tag...it's already closed)
- Updated above template code with pointers to my code files hosted on Google Pages
- Saved Blogger template
- Wrap code with pre tags as described here.
