 dnl GiNaC library version information. It has very little to do with GiNaC
 dnl version number. In particular, library version is OS dependent. 
-dnl
-dnl When making releases, do
-dnl 1. Increment ginac_lt_revision
-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 4. If any interfaces have been removed since the last release, set 
-dnl    ginac_lt_age to 0.
-dnl
-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. ;-)
