# 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.
