Command explanations
mv doc/apps/passwd.pod doc/apps/openssl-passwd.pod : We do this because otherwise openssl installs it's passwd man page over the
existing system one which isn't what we want.
make MANDIR=/usr/share/man
make MANDIR=/usr/share/man install These
commands install openssl with the man pages in /usr/share/man
instead of the default which is /etc/ssl/man.
rmdir /etc/ssl/lib : This is simply a
tidy-up command. For some reason, the openssl install routine creates
the /etc/ssl/lib directory even though the libraries have
been installed in /usr/lib. We remove it to keep things
nice and tidy!
