images.

%package devel
Summary:        Headers for the libjpeg-turbo library
Obsoletes:      libjpeg-devel < 8d-3
Provides:       libjpeg-devel = 8d-3%{?dist}
Requires:       libjpeg-turbo = %{version}-%{release}
Obsoletes:      libjpeg-turbo-static < 1.3.1
Provides:       libjpeg-turbo-static = 1.3.1%{?dist}

%description devel
This package contains header files necessary for developing programs which will
manipulate JPEG files using the libjpeg-turbo library.

%package utils
Summary:        Utilities for manipulating JPEG images
Requires:       libjpeg-turbo = %{version}-%{release}

%description utils
The libjpeg-turbo-utils package contains simple client programs for accessing
the libjpeg functions. It contains cjpeg, djpeg, jpegtran, rdjpgcom and
wrjpgcom. Cjpeg compresses an image file into JPEG format. Djpeg decompresses a
JPEG file into a regular image file. Jpegtran can perform various useful
transformations on JPEG files. Rdjpgcom displays any text comments included in a
JPEG file. Wrjpgcom inserts text comments into a JPEG file.
