Best coding practices for 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 a ROS catkin package, there will be a package.xml file. This file should contain the author's name, a description of its content, and its license.

  The following is an example of a package.xml file:

  <?xml version="1.0"?> 
  <package> 
    <name>roscpp_tutorials</name> 
   
    <version>0.6.1</version> 
   
    <description> 
      This package attempts to show the features of ROS step-by-step, 
      including using messages, servers, parameters, etc.
