#
#  1. Remember that version-info is current:revision:age, and age <= current.
#  2. If the source code has changed at all since the last public release,
#     then increment revision (`c:r:a' becomes `c:r+1:a').
#  3. If any interfaces have been added, removed, or changed since the last
#     update, increment current, and set revision to 0.
#  4. If any interfaces have been added since the last public release, then
#     increment age, since we should be backward compatible with the previous
#     version.
#  5. If any interfaces have been removed or changed since the last public
#     release, then set age to 0, since we are not backward compatible.
#  6. libtool will build libpst.so.x.y.z where the SONAME is libpst.so.x
#     and x=current-age, y=age, z=revision
