splitting file into multiple files by searching for string

[deanhystad]

Look to see if the line from the file starts with (hint hint) "[Event "Let's Play!"]".
The logic would be something like this:

Output:
output file = None
open input file
for line in file
    if line starts with "[Event "Let's Play!"]"
        if output file
            close output file
        open new output file
    if output file
        write line to output file
close input file
close output file

There are also command line tools that will do the job, like awk.
