Source Code Procurement
=======================

The package's source code is actually constructed from two different upstream
sources:

 * The C toolkit: http://naif.jpl.nasa.gov/pub/naif/toolkit//C/PC_Linux_GCC_32bit/packages/cspice.tar.Z

 * The FORTRAN toolkit: http://naif.jpl.nasa.gov/pub/naif/toolkit//FORTRAN/PC_Linux_gfortran_32bit/packages/toolkit.tar.Z

The first link corresponds to the C implementation of the library, which is the
one intended to package. However much of the C code distributed is produced by
translating FORTRAN files through f2c. Therefore the translated C files are
substituted by its corresponding FORTRAN counterparts, which are of course
obtained from the second link. Nevertheless there are 4 files which are not
produced by direct translation and are left as is:

 * rdker.c
 * zzldker.c
 * zzxlated.c
 * zzxlatei.c

Moreover upstream distributes source code and compiled binaries, all together.
This binaries are removed for compliance with the DFSG. Besides, upstream
replicates the very same header files through different subfolders, these are
also removed for the sake of simplicity.

The construction of the "upstream tarball" is made using the script
debian/repack.
