#
# Script to create the alias database
# (usually ${sysconfdir}/aliases.dat)
#
# The alias database text is usually
# ${sysconfdir}/aliases
#
# This can be either a file, or a directory. If it's a directory, all files
# in the directory are concatenated together, and the database is created
# as the result.
#
# Use -alias=foo to use "foo" instead of
# ${sysconfdir}/aliases.dat
#
# Use -src=bar to use "bar" instead of
# ${sysconfdir}/aliases
#
# Use -dump to print the raw database, without creating anything.
#
# A temporary file is used, usually
# /var/lib/courier/tmp/aliases.tmp.
# It must be on the same filesystem as aliases.dat. If -alias is used to
# point to another filesystem, specify -tmp=filename.
# Since /var/lib/courier/tmp is not globally writeable,
# -tmp must be used if a non-root runs makealiases (with other options,
# for testing purposes, perhaps).
#
# Use -chk AFTER aliases.dat has been created, with the same arguments,
# to check if the aliases include any bad addresses.
