| 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. |

| 57 | # to 0. |
