Libpng comes in several distribution formats. Get libpng-*.tar.gz,
libpng-*.tar.xz, or libpng-*.tar.bz2 if you want UNIX-style line
endings in the text files, or lpng*.7z or lpng*.zip if you want DOS-style
line endings. You can get UNIX-style line endings from the *.zip file
by using "unzip -a" but there seems to be no simple way to recover
UNIX-style line endings from the *.7z file. The *.tar.xz file is
recommended for *NIX users instead.
