[net.sources] Errata on internet code

bstempleton (12/15/82)

Oops!  There are two mistakes in the internet code.  One is that in
the descriptors for the "@" and "." key characters in the conf.c file,
the comma is missing after those characters.   The compiler will complain
if you leave them off, of course.

Secondly, the error routine in netmail.c uses a "%r" option on printf
which is a local mod here.  It lets you include a string of arguments
denoted by one so you can write front ends for printf easily.  You'll have
to either use _doprnt or handle it in your own private way.

Another note for testing this code.  Some version of ucb mail have a variable
in them called "sendmail".  If your test delivermail is in /usr/test/delivermail,
you can have a line in your .mailrc that says:

set sendmail=/usr/test/delivermail

and then when you call ucb mail it will use this version.
This is an undocumented feature of a not widely distributed version of
ucbmail, as is the "alternate" command mentionned in the document.
