I create many jobs in Deployment Solution and am often asked to export and share those jobs containing many tasks. Those who know me know that scripting an install or other action is my passion. Here's a tip to help you write useful and sharable DS jobs.
When creating a run script task, the first line of the task should be a remark (REM) followed by your description on the same line.
Here's a sample:
REM This task Changes the current working directory cd c:\windows
This will populate the details column for your task inside a job. The details column is otherwise left blank and not available as an option during the creation process.
I then use the job description to annotate a KB or or any other particulars such as -- but not limited to -- application version.
