inherit webapp eutils

# Bugs so far:
#
#	- RELEASE is looked at whenever you go to otrs/index.pl so it needs to be
#   copied to the vhost directory or the application needs to be modified to 
#   look for it in the /usr/share/doc directory
#
#	- Apache2 w/ Mod_perl seems to work but requires some significant editing
#   until I have template files or a automated way to get the necessary files 
#   to work with webapp-config or just the ebuild itself. The files that need to
#	be edited or create are:
#
#		- 76_otrs.conf which goes in /etc/apache/conf/modules.d and contains
#		the information usually placed in the apache conf file. This works well 
#		for a single installation which I'm currently testing but won't function
#		well for multiple installations so need to find a work around for that.
#
#		- apache2-perl-startup.pl needs to be edited to reflect the actual 
#		location of otrs when it is installed. As with the file above changing
#		the default script to point to the actual location works but this does
#		not work with webapp-config. I am not sure if or how mod_perl works
#		thus I am not sure if we were to call this file multiple times once per
#		vhost installation if that would bork things or not.
#
#
# added GD to iuse its used for optional stats generation

	# This DEPEND could be optimized but hasn't been, I've actually added some
	# packages which were not present (Digest-MD5, MIME-Base64, and libnet) but
	# which were a depend of the software. MIME-tools will pull in:
	#
	#	dev-perl/libnet
	#	dev-perl/MailTools
	#	dev-perl/IO-stringy
	#	dev-perl/Digest-MD5
	#	dev-perl/MIME-Base64
	#
	# So theoritically we don't need to call these by themselves though I
	# believe it is best practice to do so. MIME-Base64 isn't strictly needed
	# unless we are using perl less than 5.8

	# Following are packaged with PERL so shouldn't need to be called but
	# are noted because they are required
