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 since the last public release, then set age # to 0.
