- 1. Merge opml files, blog listings
1. | Merge opml files, blog listings |
| Dave Pawson
I've long run three different sets of blog lists on
3 different PC's. Each time I keep thinking what was
that blog on the other PC?
I've finally written a merge stylesheet.
Takes two opml files and merges them into one.
Enjoy.
