## From the libtool documentation on library versioning:
##
## CURRENT
##      The most recent interface number that this library implements.
##
## REVISION
##      The implementation number of the CURRENT interface.
##
## AGE
##      The difference between the newest and oldest interfaces that this
##      library implements.  In other words, the library implements all the
##      interface numbers in the range from number `CURRENT - AGE' to
##      `CURRENT'.
##
##    If two libraries have identical CURRENT and AGE numbers, then the
## dynamic linker chooses the library with the greater REVISION number.
##
##   1. Start with version information of `0:0:0' for each libtool library.
##
##   2. Update the version information only immediately before a public
##      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.
##
##   5. If any interfaces have been added since the last public release,
##      then increment AGE.
##
##   6. If any interfaces have been removed since the last public release,
##      then set AGE to 0.
