 Description: script file based graphical CAD environment
  OpenSCAD is a software for creating solid 3D CAD objects. It focuses on CAD
  aspects rather than artistic ones.
  .
  OpenSCAD is not an interactive modeller. Instead it is something like a
  3D-compiler that reads in a script file that describes the object and renders
  the 3D model from this script. This gives the designer full control over the
  modelling process and enables him to easily change any step in the modelling
  process or make designes that are defined by configurable parameters.

Changes:
 openscad (2014.03+dfsg-1) unstable; urgency=low
 .
   * New upstream version
     - resize module
     - scale parameter on linear_extrude
     - recursive use of modules
     - assignments can depend on previous assignments
     - syntax highlighting
     - user library path
     - support for opening dxf files
     - new behavior of preview and highlight operators
     - new diameter arguments
     - parent_module() and children() functions
     - Unicode handling
     - negative steps in ranges
     - norm() and cross() functions
     - new command line options
     - bugfixes
     - drops many test programs which caused issues when ran outside the build
       directory
   * Copyright file updates
   * Build-depend on glib
   * Build-conflict against libgles2-dev (eg libgles2-mesa-dev)
   * Patches dropped due to upstream inclusion:
     - changes to eigen.pri
   * Patch out verbose mode through qmake
   * Patch tests/CTestCustom.template to use test_pretty_print.py instead of
     the test_pretty_print.c wrapper that is just used to transport a hardcoded
     path that is not present on installed systems anyway
   * Patch tests/test_pretty_print.py to use Debian package information instead
     of unavailable git information
   * Drop scripts directory for +dfsg repackaging
   * Explicitly set OpenSCAD version from upstream version
   * Patch tests/test_cmdline_tool.py to use absolute paths (because openscad
     and echotest have different behaviors in that respect)
   * Add build dependencies to run the test suite at build time
   * Depend on openscad-mcad for building to run the test suite
     - Patch out check for MCAD subtree
   * Change Standards-Version to 3.9.5 (no further changes)
