# Rules for libtool versioning (from https://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html)
# 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.
