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