%description devel
liba52 is a free library for decoding ATSC A/52 streams. It is released
under the terms of the GPL license. The A/52 standard is used in a
variety of applications, including digital television and DVD. It is
also known as AC-3.

These are the header files and static libraries from liba52 that are needed
to build programs that use it.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "xlc -q64" or "gcc -maix64".
