A quick note to those of you who picked up the latest
MiscKit... and perhaps used tar instead of gnutar to
unpack it...
When packing, some of the pathnames were longer than 100
characters, which exceeds the limit of the standard UNIX tar
utility. As such, I used gnutar to do the packing. If you
have NEXTSTEP 3.2 (and, I think, 3.1) you have
/usr/bin/gnutar already; if you don't have it, you will need
to get it in order to properly unpack the archive.
The symptom of unpacking a gnutar archive under regular tar
is the appearance of a file named @LongLink. The file stores
the path that the previous file should be moved to, which
gnutar does as it unpacks. (The latest gnutar uses this
format; earlier versions named all the files @@MaNgLeD.xxx
and put all the real pathnames in a file at the end of the
archive.) Note that the regular tar will not place these
files in the correct places after unpacking and hence leave
you with a bit of a mess.
This is why there was a "gnutar" in the extension. For a
period of time, the MiscKit on the German ftp site did _not_
have this extension. (They renamed the file inappropriately;
I requested they put it back because of this problem, so it
should have "gnutar" in the name again by now.)
If this problem bit you, I think that the only thing that
will not work right for you is the Temp example
"QuickProject". If you can live without that, then don't
worry about unpacking things all over. But it is a cool
little app that is worth looking at... :-)
