# Upstream doesn't use a SONAME and nobody knows how stable the interface is
# Please take extra care when updating this package -- bump the following
# and rebuild dependencies (shouldn't be many) if you suspect an ABI change:
%define abi_major 0
%define abi_minor 1

%description
pnglite is a C library for loading PNG images. It was created as a substitute
for libpng in situations when libpng is more than enough. It currently requires
zlib for inflate and crc checking and it can read the most common types of PNG
images. The library has a small and simple to use interface.
