This repository contains libpng tar.xz and .7z distributions, intended for direct download via scripts containing "wget" or "curl" directives such as
wget http://github.com/glennrp/libpng-releases/raw/master/libpng-1.6.23.tar.xz
wget http://github.com/glennrp/libpng-releases/raw/master/lpng1623.7z
The *.tar.xz files contain source files with *nix-style line endings and contain a "configure" script and associated files for building a Makefile.
The *.7z files have DOS-style line endings and don't have "configure".
You can obtain the PGP armored signature for each file by appending .asc, e.g.,
wget http://github.com/glennrp/libpng-releases/raw/master/lpng1623.7z.asc
