Another possibility is to hook an image to a sources file:

Open a newChanges file

Pass 1: scan the newSources file, and for each method/class comment found
and also in image,
if sourceCode+timestamp matches, record method->new source position
else append sourceCode to new changes, record method->new changes position.

Pass 2: scan all existing method/class comment in image
if found in recorded, alter remembered sourceCode position
else  append sourceCode to new changes, alter remembered sourceCode position

changes the sources and changes to newSources and newChanges
