# 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.
