SOUP Commands - Gnus Manual

These are commands for creating and manipulating soup packets.

G s b: Pack all unread articles in the current group (gnus-group-brew-soup). This command understands the process/prefix convention.
G s w: Save all soup data files (gnus-soup-save-areas).
G s s: Send all replies from the replies packet (gnus-soup-send-replies).
G s p: Pack all files into a soup packet (gnus-soup-pack-packet).
G s r: Pack all replies into a replies packet (nnsoup-pack-replies).
O s: This summary-mode command adds the current article to a soup packet (gnus-soup-add-article). It understands the process/prefix convention (see Process/Prefix).

There are a few variables to customize where Gnus will put all these thingies:

gnus-soup-directory: Directory where Gnus will save intermediate files while composing soup packets. The default is ~/SoupBrew/.
gnus-soup-replies-directory: This is what Gnus will use as a temporary directory while sending our reply packets. ~/SoupBrew/SoupReplies/ is the default.

gnus-soup-packer: A format string command for packing a soup packet. The default is ‘tar cf - %s | gzip > $HOME/Soupout%d.tgz’.
gnus-soup-unpacker: Format string command for unpacking a soup packet. The default is ‘gunzip -c %s | tar xvf -’.
gnus-soup-packet-directory: Where Gnus will look for reply packets. The default is ~/.
