11    # The following is the libtool / shared library version. This doesn't have to
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.
24    #  6. If any interfaces have been removed since the last public release, then set age
25    #     to 0.
