#     release of your software.  More frequent updates are unnecessary,
#     and only guarantee that the current interface number gets larger
#     faster.
#
#  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, increment CURRENT, and set REVISION to 0.

#     then increment AGE.

#     then set AGE to 0.
