this top level directory contains the header files associated with
ohana library packages or basic ohana code snipets not in libraries:

fitsio.h - libFITS.h
ohana.h, Xohana.h - libohana
skycalc.h - libskycalc
loneos.h - FITS database interactions

the architecture-dependent subdirectories allow us to install
libraries for one architecture which are not needed and would conflict
on another architecture.  this is mostly a problem for solaris, which
does not have various libraries installed by default.  we can install
an older solaris version of these libraries and not cause conflicts
with the more recent linux versions:

libpng
libjpeg
libreadling
zlib
