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