+LuxBlend25 is the LuxRender's interface and export script for
+Blender 2.6x.
+LuxRender is a physically based and unbiased rendering engine.
+Based on state of the art algorithms, LuxRender simulates the flow of
+light according to physical equations, thus producing realistic images
+of photographic quality.
+
+NOTE: to use it from blender you need to activate this, specifying the
+full path to luxrender (/usr/bin/)

+# 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.
