Hello,

I believe the line:
	.jpg		image		pjpeg		-		y
should be removed.

I found another curiosity in the file.
term% grep compress /sys/lib/mimetype
.Z		-		-		compress	m
.taz		application	x-tar		compress	m
.trz		application	x-tar		compress	m
.z		-		-		compress	m
.Z		-		-		compress	m
term% 
Does this mean that file suffixes are case sensitive in determining the mime type?
If so, should files with suffix “.JPG” be renamed to “.jpg” ?
