+SFCGAL is a C++ wrapper library around CGAL, written with the aim of
+supporting ISO 19107:2013 and OGC Simple Features Access 1.2 for 3D
+operations.
+
+OpenSceneGraph is an optional dependency enabled by default if found
+in your system. If you do not need this, pass the environment variable
+to the script:
+   OSG=no ./SFCGAL.SlackBuild
+
+SFCGAL-legacy builds version 1.3.9, the lastest compatible with the 
+package CGAL available in this repository. If you keep this version
+of the dependency, you have to install this package. 
+
+If you have CGAL5 installed in your system, this package is not
+compatible and you must refer to the slackbuild SFCGAL based on 
+greater versions and also available in this repository.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
