dnl current

dnl The difference between the newest and oldest interfaces that
dnl this library implements. In other words, the library implements
dnl all the interface numbers in the range from number current -
dnl age to current.
dnl
dnl Here are a set of rules to help you update your library version
dnl 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
dnl release of your software. More frequent updates are unnecessary, and
dnl only guarantee that the current interface number gets larger faster.
dnl 3. If the library source code has changed at all since the last update,
dnl then increment revision (`c:r:a' becomes `c:r+1:a').
dnl 4. If any interfaces have been added, removed, or changed since the last
dnl update, increment current, and set revision to 0.
dnl 5. If any interfaces have been added since the last public release, then
dnl increment age.
dnl 6. If any interfaces have been removed since the last public release,
dnl then set age to 0.
