 #  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
