%description
JBIG is a highly effective lossless compression algorithm for bi-level
images (one bit per pixel), which is particularly suitable for scanned
document pages.

%description -n libjbig
JBIG is a highly effective lossless compression algorithm for bi-level
images (one bit per pixel), which is particularly suitable for scanned
document pages.

This package is required for libjbig-based programs.

%description -n libjbig-devel
JBIG is a highly effective lossless compression algorithm for bi-level
images (one bit per pixel), which is particularly suitable for scanned
document pages.

This package is only needed if you plan to develop or compile
applications which requires the libjbig library.

%description -n libjbig-devel-static
JBIG is a highly effective lossless compression algorithm for bi-level
images (one bit per pixel), which is particularly suitable for scanned
document pages.

This package contains static JBIG library.
