These tools were originally created using a set of data from
Ft. Worth, TX which made up the SECO database.  Because this
data is not being released with the GRASS system, this directory
has been cleaned out significantly, but may have some leftover
files relating to the old SECO data.  There is a set of data
being released with the GRASS spearfish location as part of the
general release.

The user should beware that these tools are linked to the Informix
DBMS, which is proprietary code.  These programs are not compiled
automatically as part of the default installation process for
GRASS, but must be compiled locally.
