I have changed my setup to write header files to $(prefix)/include/pano12 - I
wasn't sure, since the provided "makefile.*" do not install header files at
all. <http://itp.tugraz.at/~ahi/download/libpano12-autotools-2004-11-08.tar>

2:7:0 looks correct, if the interface was never changed since 2.0.0. But rule
nr 4 in <http://www.gnu.org/software/libtool/manual.html#SEC35> indicates,
that "current" will increase faster than the major release number.

Information on including a release number like 2.7.0.7 is in
<http://www.gnu.org/software/libtool/manual.html#SEC36> - the library will then be
called libpano12-2.7.0.7.so

I just checked on my system, library naming is a big mess here.

ciao,
Andreas
