CRUSH is an astronomical data reduction and imaging tool for select
astronomical cameras, such as SHARC-2, LABOCA, SABOCA, PolKa, GISMO,
SCUBA-2, SOFIA/HAWC+, and SOFIA/HIRMES.

CRUSH is written entirely in Java, allowing it to run on virtually any
platform. It provides the 'show' graphical tool for displaying FITS
images, however reductions are normally run from the command-line.

Further documentation and additional distribution formats are available
from the CRUSH website.
