mcstrans 0.2.11-2 (powerpc binary) in ubuntu jaunty

 A SE Linux security context consists of four parts, the identity (the SE Linux
 name of the "user"), the role, the domain/type, and the sensitivity.
 .
 The sensitivity label is comprised of a sensitivity level (always s0 for MCS
 and anything from s0 to s15 for MLS) and a set of categories. A ranged
 sensitivity label will have a low level and a high level where the high level
 will dominate the low level. Categories are numbered from c0 to c1023.
 .
 Names such as s0 and c1023 and not easily readable by humans, so mcstransd
 translated them to human readable labels such as SystemLow and SystemHigh.
