# The following explanation may help to understand the above rules a bit
# better: consider that there are three possible kinds of reactions from
# users of your library to changes in a shared library:
#
# 1. Programs using the previous version may use the new version as drop-in
# replacement, and programs using the new version can also work with the
# previous one. In other words, no recompiling nor relinking is needed.
# In this case, bump revision only, don't touch current nor age.
#
# 2. Programs using the previous version may use the new version as drop-in
# replacement, but programs using the new version may use APIs not
# present in the previous one. In other words, a program linking against
# the new version may fail with “unresolved symbols” if linking against
# the old version at runtime: set revision to 0, bump current and age.
#
# 3. Programs may need to be changed, recompiled, relinked in order to use
# the new version. Bump current, set revision and age to 0.
