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