# 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.
