#	2. Create the directory for the new ebuild file
#	   $ mkdir -p /usr/local/portage/net-mail/qpopper
#	3. Download this file to the directory above
#	   $ wget -P /usr/local/portage/net-mail/qpopper http://www.littlefield.info/linux/qpopper-4.0.8.ebuild
#	4. Run the following commands to perform step-by-step installation
#	   $ ebuild /usr/local/portage/net-mail/qpopper/qpopper-4.0.8.ebuild digest
#	   $ ebuild /usr/local/portage/net-mail/qpopper/qpopper-4.0.8.ebuild unpack
#	   $ ebuild /usr/local/portage/net-mail/qpopper/qpopper-4.0.8.ebuild compile
#	   $ ebuild /usr/local/portage/net-mail/qpopper/qpopper-4.0.8.ebuild install
#	   $ ebuild /usr/local/portage/net-mail/qpopper/qpopper-4.0.8.ebuild qmerge
#	   $ ebuild /usr/local/portage/net-mail/qpopper/qpopper-4.0.8.ebuild postinst
#	   $ ebuild /usr/local/portage/net-mail/qpopper/qpopper-4.0.8.ebuild clean
#	5. Check the package has successfully installed
#	   $ emerge -s qpopper
#	6. Restart the Qpopper daemon script
#	   $ /etc/init.d/qpopper restart
#	7. Check the system log
#	   $ tail /var/log/syslog
#	8. From now on, just keep your overlay files up to date and after a sync
