44 # Rules for library version information:
45 #
46 # 1. Start with version information of `0:0:0' for each libtool library.
47 # 2. Update the version information only immediately before a public release of
48 # your software. More frequent updates are unnecessary, and only guarantee
49 # that the current interface number gets larger faster.
50 # 3. If the library source code has changed at all since the last update, then
51 # increment revision (`c:r:a' becomes `c:r+1:a').
52 # 4. If any interfaces have been added, removed, or changed since the last update,
53 # increment current, and set revision to 0.
54 # 5. If any interfaces have been added since the last public release, then increment
55 # age.
56 # 6. If any interfaces have been removed since the last public release, then set age
57 # to 0.
