Go program to migrate blog posts to Hugo via RSS feed xml (specially made for micolog)

feed2md.go

//Usage:
//  First set your blog feed generate to dump all feed entries
//  $ wget http://yourdomain.com/feed -O feed.xml

// OR you can just export your data as rss 2.0 feed.
//  Then:
//  $ go run feed2md.go
// It will generate a bunch of .md files, one for each blog item. 
// Now move those items to your content dir, and you are done.
// This program will generate archetypes for hugo engine, inlcuding aliases for the old URL pattern
// The content, however, will stay as HTML code, but it is ok, Hugo just handle them nicely.
