[erlang-questions] Sending messages to multiple processes?

[Kevin]

Is there a neato idiom for sending a single message to multiple 
processes, up to say 200, or do I just need to loop it?

I also need to know they finished processing the message.  Is this the 
wrong road to go down? 

Basically I'm starting 200 processes, reading in a single file, and each 
process is fed the same line of the file one by one until the end, but 
they all handle it differently, and when they have finished all the 
lines, they spit out a modified file, and return a value to indicate 
they are finished.


Thanks for any advice,
Kevin
