# The -version-info flag accepts an argument of the form
# `current[:revision[:age]]'. So, passing `-version-info 3:12:1' sets
# current to 3, revision to 12, and age to 1.
# If either revision or age are omitted, they default to 0. Also note
# that age must be less than or equal to the current interface number.
# Here are a set of rules to help you update your library version
# information:
# 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.
