Initial Package Version: 1.2.1
Origin: none
Description: This patch will install libz.so.* to /lib instead of /usr/lib, and
it will symlink /usr/lib/libz.so to /lib. This patch replaces the following commands
from the book (chap6):
mv /usr/lib/libz.so.* /lib
ln -sf ../../lib/libz.so.1 /usr/lib/libz.so
chmod 644 /usr/lib/libz.a
Also this patch will not overwrite the man page if the sha1sum is duplicate.
