# Revision rules
# https://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html

# 1) Start with version information 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.
