[Boost-users] How to get Text Archive with CRLF after each record?

Subject: [Boost-users] How to get Text Archive with CRLF after each record?

I'm just getting one big line, no CRLF in the archive. Makes it difficult
to debug.

Interesting thing is that I was seeing CRLF in a previous archive I created
in another app. There is no difference I can detect in the way I'm archiving
in this app.
