About patching ports

[Naram Qashat]

Just a quick question really.  What's the best way to go about handling
patching of files that need PREFIX substituted into the file after the patch
has been applied?  Like for example, you replace a path in a source file
with %%PREFIX%% and you want that replaced after the patch is done.  I don't
think using SUB_FILES would work in this case.  Any help would be
appreciated.
