libswe-dev for Debian
---------------------

On Debian systems, the ephemeris files and other static data files are
located at '/usr/share/libswe/ephe/'.

Install them with the following packages:

 - swe-basic-data: contemporary epoch (1800-2399 CE), about 15M.
 - swe-standard-data: from 5401 BCE to 5399 CE, about 50M (including
   basic set).
 - swe-extra-data: from 13000 BCE to 16800 CE, about 115M (including
   basic and standard sets).
 - swe-data: meta-package including everything above.

By default, the library should search for data files in these directories
(modified SE_EPHE_PATH in swephexp.h):

 - /usr/share/libswe/ephe/
 - /usr/local/share/libswe/ephe/

Which leaves users enough options to install their own files. Optionally,
you can set the environment variable 'SE_EPHE_PATH' to override your
application's default ephemeris path. See documentation provided by the
package 'libswe-doc'.
