#  2. Update the version information only immediately before a public release of

#  3. If the library source code has changed at all since the last update, then
#     increment revision (`c:r:a' becomes `c:r+1:a').
#  4. If any interfaces have been added, removed, or changed since the last update,

#  5. If any interfaces have been added since the last public release, then increment
#     age.
