# Original Authors: Fernando J. Pereda <ferdy@gentoo.org>
# Tom Martin <slarti@gentoo.org>
#
# Purpose: eclass to intarface with net-mail/mailer-config, used to manage
# multiple MTA's installed on a Gentoo system.
#
# Usage: call mailer_install_conf in src_install(), on the condition that
# "mailwrapper" is in USE. If mailer_install_conf has no arguments,
# ${FILESDIR}/mailer.conf will be installed to /etc/mail. If it is given a file
# as argument, this will be used. Also, please note that there is no need to
# IUSE="mailwrapper" or create RDEPENDS for mailwrapper as used to be the case.
# As you can see below, these are now set by this eclass. This rule also holds
# true for PROVIDE="virtual/mta".
#
##
# Functions available for ebuilds:
#
# mailer_get_current() - Returns the current profile (i.e. postfix-2.2.3)
# mailer_install_conf() - Installs the profile file in ${1} or
# ${FILESDIR}/mailer.conf if ${1} is not specified.
# mailer_set_profile() - Sets the current profile to ${1} or to ${P} if ${1}
# is not specified.
# mailer_wipe_confs() - Removes unused profiles (i.e. the profile exists but
# the package is no longer available)
