Creating your own News Collections in nn

Study this command, entered from pegasus> or andromeda>:

        nn -shypertext -m comp.all
 
'comp.all' makes NN search all groups beginning with 'comp.' [i.e., most 
groups on the subject of 'computers.' 

'-shypertext' tells nn to search for only those messages with the 
string 'hypertext' in their subject line.  

'-m' tells nn to merge all those into a special 'MERGED NEW GROUPS.'
 
When I tried this, nn reported:
 
       Read 25073 articles in 49 seconds (42 kbyte/s)
 
and then took me to a standard nn menu for the 6 articles that it had culled
from those 25,073.  Here's the screen print:
 
MERGED NEWS GROUPS:  6 ARTICLES

Next I tried to find all the current news on hostages, with this command 
from andromeda's main prompt:
 
             nn -shostage -m clari.all
 
That one collected 11 articles from

groups, and it did so in only 11 seconds.
