10 dnl GiNaC library version information. It has very little to do with GiNaC
11 dnl version number. In particular, library version is OS dependent.
13 dnl When making releases, do
14 dnl 1. Increment ginac_lt_revision
15 dnl 2. If any interfaces have been added, removed, or changed since the last
16 dnl release, increment ginac_lt_current and set ginac_lt_revision to 0.
17 dnl 3. If any interfaces have been added since the last release, increment
19 dnl 4. If any interfaces have been removed since the last release, set
20 dnl ginac_lt_age to 0.
22 dnl Please note: the libtool naming scheme cannot guarantee that on all
23 dnl systems, the numbering is consecutive. It only guarantees that it is
24 dnl increasing. This doesn't matter, though: there is not incurred cost
25 dnl for numbers that are omitted, except for shrinking the available space
26 dnl of leftover numbers. Not something we need to worry about yet. ;-)
