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 since the last release, increment
16 dnl ginac_lt_current and set ginac_lt_revision to 0.
17 dnl 3. If any interfaces have been changed or removed since the last release,
18 dnl make sure you increment ginac_minor_version above and reset both
19 dnl ginac_lt_current and ginac_lt_revision to 0.
21 dnl Please note: the libtool naming scheme cannot guarantee that on all
22 dnl systems, the numbering is consecutive. It only guarantees that it is
23 dnl increasing. This doesn't matter, though: there is not incurred cost
24 dnl for numbers that are omitted, except for shrinking the available space
25 dnl of leftover numbers. Not something we need to worry about yet. ;-)
