description         Decompression compatible with pkunzip

long_description \
    UnZip is an extraction utility for archives compressed in .zip \
    format (also called \"zipfiles\"). Although highly compatible both \
    with PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's \
    own Zip program, our primary objectives have been portability and \
    non-MSDOS functionality.
