-dnl 2. If any interfaces have been added, removed, or changed since the last
-dnl release, increment ginac_lt_current and set ginac_lt_revision to 0.
-dnl 3. If any interfaces have been added since the last release, increment
-dnl ginac_lt_age.

dnl Please note: the libtool naming scheme cannot guarantee that on all
dnl systems, the numbering is consecutive. It only guarantees that it is
dnl increasing. This doesn't matter, though: there is not incurred cost
dnl for numbers that are omitted, except for shrinking the available space
dnl of leftover numbers. Not something we need to worry about yet. ;-)
