Directory tree of the gag software:
===================================


./export                     The compressed archive files 
                             (*.tar.Z + ephemeris.tar + make-macros.* + README)
                             The ./export directory can be deleted after installation.


./sou                        Base directory of the sources 
                             Each subdirectory contains RCS files (*.for,v or *.c,v or *.tex,v
                             or *.nroff,v) that include the source code. Each subdirectory
                             has an equivalent in the ./exe tree. The whole ./sou tree can
                             be deleted after installation.
