# library versioning
# (quoted from libtool doc)
# 1. Update the version information only immediately before a public release
# 2. If the library source code has changed at all since the last update,
# then increment revision (`c:r:a' becomes `c:r+1:a').
# 3. If any interfaces have been added, removed, or changed since the last
# update, increment current, and set revision to 0.
# 4. If any interfaces have been added since the last public release,
# then increment age.
# 5. If any interfaces have been removed since the last public release,
# then set age to 0.
