Subject: pwclient: add output format option to list/search command
X-Git-Url: http://git.ozlabs.org/?a=commitdiff_plain;h=4f152d818977fb6a9f1ca1b38f88253cf61a8c73;p=patchwork

pwclient: add output format option to list/search command

Make scripting easier by letting the user specify the output format. The
format string may contain tag references to fields, such as %{id} and
%{msgid}.
