Think sed, and do yourself a huge favor and find a really experienced sed 
user because with the complexity of what you want to do now, that will 
probably be your best insurance against not leaving your project in a 
total mess.  If you must do all of this yourself, please consider sending 
blank email to address@hidden and ask some questions 
on that email list before you take definitive action on your project.  
Also, remember there are people who belive in the religion of backups and 
then there are people who are going to get religion.  The sed-users email 
list is usually high signal and low noise and usually low volume in terms 
of traffic passed.
