[ros-users] 5 Reasons ROS Users Will Want to Try catkin_tools Beta 2!

[Jonathan Bohren]

Today, the ROS Community Build Tool Team has released the second
catkin_tools beta, Version 0.4.0!

*Previously, a quick summary:*
- `catkin_tools` is an improved toolchain for building catkin workspaces
- the CLI command is `catkin build`
- it builds packages in parallel with isolated build directories (no CMake
crosstalk)
- it builds "pure" CMake packages that don't use Catkin macros
- it lets you build subsets of a workspace
- it needs to be tested more before being recommended over `catkin_make`
- the documentation for all the additional features can be found here:
http://catkin-tools.readthedocs.org/

*The top five reasons you'll want to try Beta 2:*
1. The ability to reliably clean parts of your workspace without rebuilding
everything!

2. A new warning and error display!

3. New ways to quickly move to and source a workspace!

4. A new asynchronous execution model for building and cleaning!
