%description
librsync implements the "rsync" algorithm, which allows remote
differencing of binary files. librsync computes a delta relative to a
file's checksum, so the two files need not both be present to generate
a delta.

This library was previously known as libhsync up to version 0.9.0.

The current version of this package does not implement the rsync
network protocol and uses a delta format slightly more efficient than
and incompatible with rsync 2.4.6.

The library is available as 32-bit and 64-bit.

%description devel
This package contains header files necessary for developing programs
based on librsync. It was previously known as libhsync up to version
0.9.0.

The current version of this package does not implement the rsync
network protocol and uses a delta format slightly more efficient than
and incompatible with rsync 2.4.6.

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_r -q64" or "gcc -maix64".
