annotate src/accept.c @ 156:ee2afbf92428

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
require host_name to be set in config file exit otherwise there is no portable way to determine the hostname (actually the hostname that masqmail should use) thus it must be set by the administrator
