- : newnewsrc - make a new .newsrc conform to an old one.
- : Col. G. L. Sicherman. 7 Aug 1985.
- :
- : Have you ever moved from one system to another and found that
- : you must customize a whole new .newsrc, because the old system
- : numbered its news articles differently?
- : This script imposes as much of an old .newsrc as possible on
- : a new .newsrc. Specifically, it disables groups that were
- : disabled on the old system, and arranges groups into the old
- : order.
- :
- : usage: newnewsrc [-e] [-b] [-o] OLD NEW
- :
- : -e Enable disabled groups on NEW that were enabled on OLD.
- : -b Place groups not found on OLD at beginning of NEW
- : rather than at end.
- : -o Do not import "option" lines from OLD.
- :
- : New file is written to standard output.
