SVN script for automatically adding and deleting files

Add a line from 1 file after every line of another (shuffle files together)
After every line in targetfile (empty lines included) insert in a line from addfile. "Save" results to savefile. Addfile should be longer than targetfile since this doesn't loop back to the top of addfile. /^/R addfile -- says for every line that matches "has a start of line" output a line from the file addfile. > savefile (optional) -- redirect output to savefile file.

This group of lines is then sent as notification to the user. You can test the example with $ logger "First group"; sleep 1; logger "Second"; logger "group"
