[plug] Insert one file into another

[Ben New]

Derek,

cat file1 | sed -e '/>>>>.*/ r file2' | sed -e '/>>>>.*/ d'

I'm sure the above can be achieved in only one call to sed...  But the 
above should work anyway, even if it's not particularly efficient.  
(That is, assuming the marker line does start with '>>>>' and the files 
are called 'file1' and 'file2').

In case you were wondering, the first call inserts the (entire) contents 
of file2 after the marker line, the second call removes the marker line.

Regards,
Ben
