days remaining to the GSoC proposal submission deadline.

I request the mentors and everyone in the community who has experience in
RTEMS, to please go through my proposal for Coverage Analysis tool
improvement project , if they have time , and suggest any kind of
improvements and changes .
here is the link to the proposal
https://docs.google.com/document/d/1UjCWE1ojrpDQLQ2fQqxHU0SCrLETlerxD6t0SOcQNLQ/edit?usp=sharing
Thank you
