12    # The following is the libtool / shared library version. This doesn't have to
13    # do anything with the release version. It MUST conform to the following rules:
14    #
15    #  1. Start with version information of `0:0:0' for each libtool library.
16    #  2. Update the version information only immediately before a public release of
17    #     your software. More frequent updates are unnecessary, and only guarantee
18    #     that the current interface number gets larger faster.
19    #  3. If the library source code has changed at all since the last update, then
20    #     increment revision (`c:r:a' becomes `c:r+1:a').
21    #  4. If any interfaces have been added, removed, or changed since the last update,
22    #     increment current, and set revision to 0.
23    #  5. If any interfaces have been added since the last public release, then increment
24    #     age.
25    #  6. If any interfaces have been removed since the last public release, then set age
26    #     to 0.
