# Libtool 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'.
#
# Rules:
#  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.
