dnl Rules for library version information:
|

|
|
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.
|
||
|
