4 fa325e9b 2020-01-10 cross * installation CDs that double as valid Plan 9 disk partitions.

6 6f4d00ee 2013-09-23 0intro * partition and you've got a working Plan 9 system.
8 6f4d00ee 2013-09-23 0intro * I've tried hard to keep all the associated cruft in this file.
9 6f4d00ee 2013-09-23 0intro * If you deleted this file and cut out the three calls into it from flfmt.c,
10 6f4d00ee 2013-09-23 0intro * no traces would remain.
