Want to know the actions done by the string assigned to bootcmd

Hi,

I am using mini2440 1GB board.

In Forrest's Blog I see in the final step we are saving the value of
bootcmd env variable while using Uboot to download softwares.

For bootcmd environment variable we are assigning the following string:

nboot.e kernel \; bootm

I want to know what it will expand to and what actions will it do?

Where I can decipher that string?

Please reply!
