Pull in some wording to the tftpd.8 man page
from NetBSD, with some slight changes:
=========================================================================================
http://cvsweb.netbsd.org/bsdweb.cgi/src/libexec/tftpd/tftpd.8?only_with_tag=MAIN#rev1.22
Revision 1.22 or diffs], Fri Jan 8 21:05:14 2010 UTC (18 months, 2 weeks ago) by christos
Patrick Welche <prlw1@cam.ac.uk>
- add -p pathsep option
- make wrap to zero work, but produce a warning
While here:
- fix gcc warnings, in particular variable clobbered warnings
(compiling with fewer warnings does not really fix the problem)
=========================================================================================
These wording changes clarify the default rollover behavior
as a "kludge". Also, the block numbers and octet counts for 65535 blocks
and 32767 blocks are more accurate than the existing documented numbers.
