[ale] mass file modifcation

[Jim Popovitch]

I need to update about 43k files and sed just won't cut it for this
task.   What I need to do is replace 2 lines with 4 new ones, and the
lines contain URLs (backslashes, brackets, etc.).  What I would like
to do is put the new text in a file and pass it and the search text to
some program that will modify all the files.   Any ideas on whats
available to do that?

Thx,

-Jim P.
