Grab Flickr data

Write Linux/UNIX shell script to get results of a search from Flickr as an XML file, parse it and display payloads as HTML.
Can be done in 40 lines of shell or so.

1. Flickr services
   • feeds (RSS or Atom)
     • public content
     • e.g. Search for a feed of the latest images tagged with Paris

2. Shell script usage: flickr (tag)
3. Gets XML feed of latest photos tagged with this tag. Looks like this.
4. Extract these items:

   <content type="html">
    quoted HTML payload
   </content>
   

5. Convert payloads to normal HTML.
6. See sed, tr, etc.
7. See Parsing XML / HTML
8. Output just those payloads (images linking to original) to $HOME/tmp/flickr.html
