Hi Sankar,

I started with something like that. Although I wrote just a bit more
complex but it really is quite simple. If you want you can use this
and I'll also like to contribute to it.

https://github.com/pranjas/psfs.git

Checkout psfs.h and psfs-format.c for complete details. Let me know if
you need any help.
