desc for execution of scripts on system startup added

Issue #1

[aquatiko]

Thanks for the PR!
Couple of things to fix:

• Please remove this file from commit. Looks redundant to me.
• The corn job is what I was expecting from the issue.(Good thinking) But the current implementation runs the job on a fixed time specified by the user. We want it to be executed on system startup. Try to come up with action based cron.
• Also, when you do finish can you add an example too? (why not use the taskkiller.sh for this?)
• Maybe add a description in PR explaining how cron solves this issue.
• (Bonus) Squash all commits into one.
