-%description
-This tool allows the extraction of InstallShield format cabinet files (which
-are different from Microsoft cabinet files). It was initially developed as a
-part of the SynCE project to aid with installing applications for Pocket PC
-devices, which were often contained in InstallShield installers, but these days
-that is rather less likely to be the primary use case.
