-This section should be replaced, if necessary, by changes to the program
-that are necessary to make \.{VPtoVF} work at a particular installation.
-It is usually best to design your change file so that all changes to
-previous sections preserve the section numbering; then everybody's version
-will be consistent with the printed program. More extensive changes,
-which introduce new sections, can be inserted here; then only the index
-itself will get a new section number.
