Changes since 1.12:
- NEW: jdb added to the freebsd ports tree
maintainer: larse@isi.edu
- BUG FIX: properly handle trailing spaces when data must be numeric
(ex. dbstats with -FS, see test dbstats_trailing_spaces)
Fix from Ning Xu .

Brannon), and list format documented in the README.
- NEW: cgi_to_db convergs CGI.pm-format storage to jdb list format

- ENHANCEMENT: "talking about columns" section added to README.
Lack of documentation pointed out by Lars Eggert.
- CHANGE: dbformmail now defaults to using Mail ("Berkeley Mail")

fine with unicode
