Ok.

Examine the source code of the files and programs to see what might need
to change.  Change it, then recompile the source code.  If errors,
update the source code until it compiles.  Then, test it to insure it
works correctly.  

Or if you wish to automate the process, source code is stored in files,
so it *can* be updated with a program.  

Figure out what kind of output you want.
Examine the type of input you have.
Write a program or programs that convert the input you have into the
output you desire.  
Compile and Test, as above.

Work from a copy!

Can't give much more advice as your query is quite generalized.
