the parser calls aclParseACLLine, which then creates new acls' as
needed.
outgoing address is initialised by it's own parser in a like fashion.
See cf.data.pre for the TYPE field, and from there look in cf_parser.h.
I think this is in the programmers guide - have you read it?

data is used by the type-specific acl code, and cfgline is the first
line seen with this acl on it, for debug purposes.

The acl IP matching code uses the acl data field to store it set of
acl_ip_data entries.
