README="""
This is generated system info, generated by the sysinfo script on http://github.com/meghuizen/systeminfo

This helps developers to get complete Linux system information, so they could detect problems.

Just run this script and you get a directory structure and a tarball in a mktemp dir, which you can upload.

it has the following structure:
		/
		| proc/ - /proc dump (not complete dump, but specific parts)
		| sys/ - /sys dump (not complete dump, but specific parts)
		| kernel/ - kernel info
		| harddrivers/ - harddrive info
					 | sdX/ - harddrive info for this specific block device
					 	  | sys-queue/ - /sys/block/sdX/queue data. Used by the IO scheduler
		| README.txt - this explanation
		| SUMMARY.txt - the summary of the system generated on it
