# 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 or changed since the last public
#    release, then set age to 0.
