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) ## IUSE="mailwrapper" RDEPEND="mailwrapper?
