The following reply was made to PR docs/42762; it has been noted by GNATS. From: Brian Somers <brian@FreeBSD.org> To: Peter Pentchev <roam@ringlet.net> Cc: AIDA Shinra <aida-s@jcom.home.ne.jp>, bug-followup@FreeBSD.org Subject: Re: docs/42762: ppp.8 has no description of $env and ~user expansion in ppp.conf Date: Thu, 16 Dec 2004 15:50:56 +0000 Oops, lost in my inbox :( Sorry. I guess there are three things to be described here. $var - as described ~ - as described ~user - the home directory of ``user''. Please feel free to commit when you can - after adding the last bit... Cheers.
