# 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.
