SpatiaLite is an open source library intended to extend the SQLite core
to support fully fledged Spatial SQL capabilities. SpatiaLite is smoothly
integrated into SQLite to provide a complete and powerful Spatial DBMS
(mostly OGC-SFS compliant). Using SQLite + SpatiaLite you can effectively
deploy an alternative open source Spatial DBMS roughly equivalent to
PostgreSQL + PostGIS.

Required dependency:
 * SQLite 3 (http://www.sqlite.org)

Recommended dependensies (enabled by default):
 * Proj.4 (http://trac.osgeo.org/proj/), available at SlackBuilds.org
 * GEOS (http://trac.osgeo.org/geos/), available at SlackBuilds.org

Optional dependency (enabled by default):
 * FreeXL (https://www.gaia-gis.it/FreeXL/)

If you don't want to build SpatiaLite with FreeXL support specify FREEXL=no
to SlackBuild, for example

  FREEXL=no sh libspatialite.SlackBuild
