# For information on how to properly maintain the library version information,
# refer to the libtool manual, section "Updating library version information":
# 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 existing interfaces have been removed or changed since the last public release, then set age to 0.
