sporadic errors from tar

[Randall R Schulz]

Fred,

Ignore those errors. They're a result of a race condition between "tar" and 
the "gunzip" sub-process forked to handle the compressed archive and the 
fact that there's some ignored trailing byes in the uncompressed data 
stream coming from gunzip. The "-B" flag to tar might suppress this message.

The way I search the User Guide or API document is by using "egrep -l" on 
the HTML files then opening the files with hits in my browser. I do it so 
infrequently I have not tried to script it, but it would not be difficult.
