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