archdetect-deb 1.87ubuntu1 (amd64 binary) in ubuntu precise

 This package provides the 'archdetect' tool, which displays the current
 machine architecture and subarchitecture. The architecture corresponds to
 that built into dpkg, and describes the CPU (and possibly kernel) types;
 the subarchitecture distinguishes machines with different boot arrangements
 that require special handling.
 .
 This package would be called 'archdetect', but a udeb of that name already
 existed for use in the installer.
