+MeshLab is an open source, portable, and extensible system for the
+processing and editing of unstructured 3D triangular meshes. The system is
+aimed to help the processing of the typical not-so-small unstructured
+models arising in 3D scanning, providing a set of tools for editing,
+cleaning, healing, inspecting, rendering and converting this kind of mesh.

+# 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.

+meshlab: meshlab (process and edit unstructured 3D triangular meshes)
+meshlab:
+meshlab: MeshLab is an open source, portable, and extensible system for the
+meshlab: processing and editing of unstructured 3D triangular meshes. The
+meshlab: system is aimed to help the processing of the typical not-so-small
+meshlab: unstructured models arising in 3D scanning, providing a set of tools
+meshlab: for editing, cleaning, healing, inspecting, rendering and converting
+meshlab: this kind of mesh.
