  6. The flow of news articles through
  7. C news
  8. is as follows:
  9. a batch is received by some network service
  10. (typically
  11. .I uucp
  12. or
  13. .I nntp )
  14. and passed to
  15. .I rnews ,
  16. .Ix rnews
  17. which invokes
  18. .I $NEWSBIN/input/newsspool
  19. .Ix newsspool
  20. to queue the batch in
  21. .B $NEWSARTS/in.coming ;
  22. .Ix in.coming
  23. .Ix files in.coming
  24. eventually
  25. .I $NEWSBIN/input/newsrun
  26. .Ix newsrun
  27. will be run by
  28. .I cron ,
  29. .Ix cron
  30. .I newsrun
  31. uncompresses any files in
  32. .B in.coming
  33. and
  34. either hands the batch to
  35. .I $NEWBIN/relay/relaynews
  36. .Ix relaynews
  37. locally or invokes
  38. .I relaynews
  39. over a network connection on its file server.
  40. .PP
  41. .I relaynews
  42. writes the name of each spool file onto the ends of batch files
  43. for neighbours.
  44. Eventually
  45. .I cron
  46. runs
  47. .I $NEWSBIN/batch/sendbatches ,
  48. .Ix sendbatches
  49. which
  50. batches up the outgoing articles and transmits them over some network.
