Best practices in the ROS package

The following are the key points to bear in mind while creating and maintaining a package:

• Version control: ROS supports version control using Git, Mercurial, and Subversion. We can host our code in GitHub and Bitbucket. Most of the ROS packages are in GitHub.
• Packaging: Inside an ROS catkin package, there will be a package.xml, and this file should contain the author name, description, and license.
  The following is an example of a package.xml:

<?xml version="1.0"?> 
<package> 
  <name>roscpp_tutorials</name> 
 
  <version>0.6.1</version>

    including using messages, servers, parameters, etc.
