# The following is the libtool / shared library version. This doesn't have to |
12 |
|
# do anything with the release version. It MUST conform to the following rules: |
13 |
|
# |
14 |
|
# 1. Start with version information of `0:0:0' for each libtool library. |
15 |
|
# 2. Update the version information only immediately before a public release of |
16 |
|
# your software. More frequent updates are unnecessary, and only guarantee |
17 |
|
# that the current interface number gets larger faster. |
18 |
|
# 3. If the library source code has changed at all since the last update, then |
19 |
|
# increment revision (`c:r:a' becomes `c:r+1:a'). |
20 |
|
# 4. If any interfaces have been added, removed, or changed since the last update, |
21 |
|
# increment current, and set revision to 0. |
22 |
|
# 5. If any interfaces have been added since the last public release, then increment |
23 |
|
# age. |
24 |
|
# 6. If any interfaces have been removed since the last public release, then set age |
25 |

# to 0. |
