12     # do anything with the release version. It MUST conform to the following rules:
13     #
14     # 1. Start with version information of `0:0:0' for each libtool library.
15     # 2. Update the version information only immediately before a public release of
16     # your software. More frequent updates are unnecessary, and only guarantee
17     # that the current interface number gets larger faster.
18     # 3. If the library source code has changed at all since the last update, then
19     # increment revision (`c:r:a' becomes `c:r+1:a').
20     # 4. If any interfaces have been added, removed, or changed since the last update,
21     # increment current, and set revision to 0.
22     # 5. If any interfaces have been added since the last public release, then increment
23     # age.
